-
so it looks like Griggree works like
-
Gri like Gri So let's do some of those
-
strange experiments and figure out if it
-
is a Grigree And to make things complete
-
I will also include Neox into the mix
-
also known as Gri And in case you want a
-
TLDDR version when it comes to cam
-
assisted devices Pinch is probably the
-
best alternative to Gri right now And if
-
you want to know if it is better than
-
Gri then the answer is not that simple
-
So let's see All right So the only truly
-
unique feature of this device is that
-
you can attach it directly to the
-
harness without the need of extra
-
carabiner which I thought it's a super
-
cool idea However what everybody
-
instantly notices that this button which
-
releases the device is not multi-action
-
So it's pretty easy to press on it and
-
remove the device So the question is can
-
that happen during the blaying and Edid
-
got bombarded by this question Oh yeah I
-
don't know how often I saw this and
-
honestly I was quite surprised that this
-
is the first thing people think of and
-
also with what passive aggressive
-
criticism this gets So yeah if you worry
-
about safety you are passive
-
aggressive But since my name got there
-
somehow I feel I have a duty now So to
-
investigate this let's divide it into
-
four possible states First when the
-
device is loaded then the device is
-
unloaded and the transition between
-
these two states So let's begin with
-
unloaded scenario And let's see what
-
Ederlid has to say about that Could I
-
accidentally open the device in an
-
unloaded scenario and the answer to this
-
is no It is simply impossible when you
-
are attentive and you operate the device
-
as shown in the user's manual So
-
understood Read the friendly manual and
-
then it's safe But um yeah before Phil
-
starts hating me let's look into this
-
deeper So there is actually only one
-
spot where I can press the button It's
-
right here If I start pressing somewhere
-
else nothing happens And this button is
-
nicely flush with the plastic round So
-
pressing from the sides nothing happens
-
Plus the button has pretty stiff spring
-
You need to press it quite hard to open
-
If the device is unloaded and I would
-
try to press the button I'm simply going
-
to push the device to the side and
-
nothing is going to happen Even if I try
-
to poke it really hard Ow ow ow ow ow So
-
the only way I can imagine pressing that
-
button in unloaded scenario is if I
-
would I don't know get knocked by the
-
rock fall on the ground and somehow
-
press on that button and release the
-
device How likely for that is to
-
happen probably not very okay Next
-
scenario The device is loaded Well I'm
-
trying to load it now I can press the
-
button Okay But I cannot open the
-
device
-
Well apparently I
-
can That was not planned That was first
-
attempt Ah okay See what happens And I
-
was pulling down on the brake strand
-
really hard and then it got loaded But
-
it got loaded in this downwards facing
-
direction and then somehow by pushing on
-
the button I managed to slip the sling a
-
little bit and now I can open it
-
Normally if the load is really high
-
probably I would not be able to pull the
-
device down as much and then in this
-
scenario if I press the button and I
-
would try to open it it would not open
-
because there is this little extra lip
-
which is hooking on the blay loop So
-
here is actually a good moment to talk
-
that there is a limit on blay loop width
-
If it's too wide it's not good cuz
-
device will sit sideways But if it's
-
very skinny like the one that I have
-
right now then it's more likely that the
-
loop could sit in some strange
-
orientation So I would be more cautious
-
with super skinny harnesses like this
-
one Now what if the device is loaded I
-
press the button and in that moment
-
somehow it would unload Could it uncip
-
at this moment
-
well I wouldn't say no but at the same
-
time it's very very unlikely So yeah
-
personally with this super skinny ble
-
loop I was using this device with a
-
backup carabiner maybe a thicker blay
-
loops my monkey brain would be happier
-
However I'm certain that if this button
-
would be double action then I would be
-
much happier Also this direct attachment
-
to the harness requires a little bit
-
more attention I had a viewer of mine
-
send me a picture where he accidentally
-
clipped like this which I can see how
-
that can happen quite easily where the
-
rope runs like so Also if you don't pay
-
attention and you have very skinny ble
-
loop you can accidentally close it like
-
so And you might not notice this And
-
this is very dangerous because it can
-
easily open So yeah pay attention and do
-
the double check before you start
-
climbing always Alternatively you of
-
course have an option to attach it with
-
the carabiner like any other blay device
-
However in this case pinch sits really
-
far from the harness cuz it actually has
-
this lip which is longer than on most of
-
blaying devices and it becomes really
-
uncomfortable to use and it kind of
-
defeats the main benefit of pinch
-
So yeah All right Now before we go to
-
actual benefits of direct attachment to
-
the harness let me first debunk one kind
-
of myth Now that you can give more slack
-
this way when the device is close to the
-
harness This is actually the opposite So
-
if I have a grigree and I give slack
-
like this Yes now I can give a little
-
bit less slack But guess what i can push
-
gri down giving much more slack So I
-
pull the rope and push the device down
-
This is actually a very cool technique
-
for short climbers or short arm
-
bellayers And before my comment section
-
explodes I have to say that there is
-
multiple ways to give slack You can do
-
this you can do that And I'm not here to
-
debate which method is the best the
-
safest However I will compare every
-
device in all of these methods So no
-
matter what you use or what you like you
-
will know which device is the best for
-
you So back to the pinch directly
-
attached to the harness And the main
-
benefit of that is that it's closer to
-
the harness is less floppy around And
-
when it falls down it does not fall as
-
much down So it makes it much easier to
-
find blindly with your hands And this
-
brings me to the first mistake where I
-
try to use pinch like I would use gri
-
where I would take my index finger and
-
hook under this lip and give slack like
-
this However you quickly realize that
-
this lip is way too small and it's not
-
comfortable to hook with index finger
-
Then I started grabbing with my thumb
-
around like this And actually this is
-
not how pinch is supposed to be bellayed
-
So with pinch you're supposed to have
-
all your fingers wrapped around the rope
-
and use only the thumb to gently press
-
on the cam and give slack like this And
-
this works really really well So
-
objectively thinking four fingers is
-
more than three And it also encourages
-
you to not touch the device when you
-
don't need it So it must be a little bit
-
safer While on contrast with Gri if I
-
hook my finger here and I relax too much
-
I might not actually hold the rope at
-
all And I already made a video of what
-
can happen in that scenario
-
So don't get too lazy and actually hold
-
the rope especially with super skinny
-
ropes All right So how does the pinch
-
work in practice the first thing I
-
noticed that it pinch is pretty heavy
-
and it's front heavy because it has a
-
steel insert in the front So after you
-
give slack it will fall down It does not
-
fall down as much as the giri cuz it's
-
closer to the harness but it does fall
-
down and there is no way to stop that
-
cuz you're not supposed to be hooking on
-
it So every time you give slack it falls
-
down and then you have to blindly find
-
the rope again and give slack So at
-
first this was kind of uncomfortable but
-
I thought that the longer I will use it
-
the more I will get used to it and
-
eventually it's going to be fine And
-
after using it for quite a while
-
delaying my partners projecting
-
different routes eventually I kind of
-
got used to this However the first time
-
I switched back to Griggi I instantly
-
felt how much easier it is to give slack
-
for me Then you give slack like this and
-
the device doesn't fall anywhere at all
-
So the first takeaway if you are a
-
Grigree user and you like giving slack
-
like this stay with Griggree If you're
-
someone who doesn't like this idea of
-
having hands close to Blay device then
-
pinch is much better option Now in case
-
you like giving slack like this in a
-
tube
-
style style then I actually tested all
-
the devices with different rope
-
thicknesses We have skinny ropes it
-
doesn't matter All the devices work very
-
well with skinny ropes Once the ropes
-
get slightly thicker to like
-
9.5 then Gri becomes unreliable It
-
starts locking up too much While pinch
-
was working really well However the king
-
of the hill was Neox cuz it's pretty
-
much designed to be blayed like this
-
It's incredibly smooth Even with the
-
ropes up to like 10 mm it's still super
-
smooth So if that's how you blay then
-
Nox is your best blay device Okay Now
-
one thing that I did not like about the
-
pinch that it felt that it takes more
-
effort to pull the rope through I asked
-
you guys and some of you said that
-
actually pinch is much smoother than gri
-
However others said that pulling the
-
rope through pinch feels like doing
-
chores So first I wanted to measure how
-
much internal friction each device has I
-
kept adding weights and checking when
-
the rope started to slip First
-
observation was that my old grigy had
-
slightly lower friction compared to
-
brand new one This is probably due to
-
smoothening and rounded edges and I
-
should probably retire this gri already
-
and pinch depending on the rope had up
-
to 30% more friction compared to a brand
-
new Griggree Now I was expecting that
-
Neox will beat all of these devices
-
However that is surprising Turns out
-
that my Neox had so much dust that the
-
wheel does not spin as smooth as it used
-
to So I did buy a new Neox nice black
-
one I like it And it is actually
-
significantly smoother It's crazy
-
smooth So I contacted Pzel and asked how
-
to clean my old Neox And once I get a
-
response I will try and see if cleaning
-
helps or actually Neox's have some dirty
-
issues So I'm going to make a separate
-
video on that Now I did not want to rely
-
on a single ugabooga test so I did
-
another one This time I wanted to
-
measure how much energy it takes to give
-
one arm of slack To make things as equal
-
as possible for the gri I used a tiny
-
tiny carabiner This way the amount of
-
rope pulled through all the devices is
-
very similar And then I used a small
-
load cell to measure the forces over
-
time which should give me this value
-
Man this is significantly harder Now as
-
you can imagine having consistency in
-
such tests is really difficult That's
-
why I needed a lot of samples a lot of
-
data points to reach statistically
-
significant numbers Wow my shoulder is
-
working on this device Also I had an
-
unexpected discovery that such way of
-
giving and taking slack many many times
-
macaroni causes many many tangles in the
-
rope which I had to remove before every
-
experiment So yeah new Neos this time
-
felt the smoothest and that's a
-
difference very closely followed by
-
Gri and pinch was double the trouble
-
This feels much
-
harder All right next up Now I'm going
-
to regret this This is 10 mm rope I
-
already feel my shoulder from
-
9.5 So with 10 mm rope Griggy was hard
-
to
-
use Definitely
-
usable Not easy though but
-
usable But pinch was another level Let's
-
see how this
-
goes Oh yeah
-
It's an actual workout
-
now However Neox was impressive in a
-
good way Okay new
-
cre Oh
-
wow
-
Okay that's
-
nice Oh it locks Now taking the slack
-
felt really great with pinch There was
-
no back slip at all However when it
-
comes to lowering I had antipanic
-
engaging all the time
-
Wow it's or and yes you can override it
-
by pulling the lever even more which
-
works well However in certain projecting
-
situations when the climbber asks to
-
lower just a bit and antipanic kicks in
-
it causes a jarring experience both for
-
the climbber and for the bare Now good
-
part is that you can actually disable
-
this antipanic feature by inserting a
-
little screw that came into the package
-
And unfortunately for me um I had no
-
idea what that screw is when I got the
-
device and now I have no idea where that
-
screw is Moving forward the front of the
-
pinch has a steel insert So if you let
-
the rope run through that it should make
-
the device last much longer unlike the
-
Grig where it develops grooves over the
-
edge It should also provide more control
-
in lowering with skinnier ropes However
-
from my testing I could barely feel a
-
difference So this steel insert is a
-
nice addition However I do slightly
-
prefer having my hand on the side when
-
lowering So I would prefer having steel
-
on the side like Gri Plus has and maybe
-
a little bit less when in the front to
-
have less weight All right next
-
experiment Ready yeah
-
I mean done So I have done a bunch of
-
these tests with Gri in the past and it
-
pretty much imitates of what happens if
-
you don't hold the rope and there was no
-
slack in the system in the beginning
-
Basically first attempt and it already
-
slipped
-
and nothing Just for comparison let's
-
compare against Gri And then let's
-
compare against
-
Gri Ah I need a
-
carabiner Ah see how great the pinch is
-
You don't even need a carabiner Oh yes
-
Swing it so it falls straight on my head
-
and kills me And this is gri
-
Yeah I've done this in the past a lot A
-
lot a lot And it's possible to make it
-
completely slip
-
but way
-
harder Okay just
-
for sake of comparison this is
-
criy Some people asked why it's why I
-
call it creek Let's go
-
I think this is even worse than pinch It
-
seemed like it's falling much
-
faster
-
Yes This is definitely more sketchy Now
-
every time I do these tests someone will
-
complain that I'm using too low weights
-
But I have already explained in my
-
physics of Griggree video how friction
-
affects the forces So I highly recommend
-
to watch that video But long story short
-
with enough friction your climbber
-
becomes very light Let's maybe try with
-
more weight because there's always
-
people complaining about me using low
-
weights Oh sheesh
-
It's not going to kill
-
me I guess I'm not going to try that
-
with
-
Neox Or should I you should I
-
should [ __ ] Now it's a bit sketchy
-
Okay this is
-
definitely much more
-
sketchy So when it comes to this test
-
Griggy was the safest followed by pinch
-
and Neox was the most likely to slip So
-
I got a comment that catches with pinch
-
felt harder than catches with gri So
-
what I'm going to try is to measure the
-
forces I am a bit skeptical about this I
-
mean when Gri catches there is the
-
carabiner which moves up so maybe that
-
plays a role
-
Three
-
four Okay
-
077
-
3
-
4 6 Exactly the
-
same
-
68 So I'm getting consistent results
-
It's not even like that It's
-
progressively loading It's just
-
goes The only difference would be if
-
there would be different slippage in the
-
device But both of these devices seem to
-
have similar slippage which is very
-
little
-
So equal However what should play more
-
of a bigger effect is doing a proper
-
soft catch It's a bit silly to even try
-
on this uh test setup but let's see if I
-
can do
-
anything Half
-
035 compared to the previous one So
-
that's a good illustration how soft
-
catch plays a much bigger role And
-
actually my next video is going to be
-
about soft catches and catching falls
-
for my blay master class So stay tuned
-
All right So
-
takeaways grigree is definitely smoother
-
to pull the rope through However this is
-
only noticeable on thicker ropes like
-
9.5 or above or some older fuzzier ropes
-
Now if you bellayed in the past with gri
-
and you like this index finger hooking
-
on the lip to pay with slack by gri stay
-
with gri be happy with gri However if
-
you're not a fan of touching the blaying
-
device then pinch is definitely an
-
amazing alternative for you It works
-
surprisingly well Very nice And I would
-
pick
-
Neos if I would primarily delay like
-
this or I would use very very thick
-
beefy ropes like 10 mm or above ropes
-
It's only usable with Neox And before we
-
finish I wanted to share a story with
-
you When I was in university I had a
-
calculus teacher who was probably one of
-
the best teachers we had back then there
-
And that teacher worked at a bank at a
-
high position in a bank So he was making
-
much more money in his bank job than
-
teaching us And because of that one day
-
somebody asked him like hey what's the
-
point for you to come here every year
-
and teach us when you are already there
-
in your glamorous life and his answer
-
actually stuck to me till this day He
-
said well it's an exercise for my brain
-
and I don't want to forget the basics So
-
yeah for me that was a very nice message
-
to never stop learning and that's why
-
I've been happily using and promoting
-
the sponsor of today's video Brilliant
-
Brilliant is a learning app that can
-
transform your little downtime moments
-
into learning opportunities It has
-
thousands of short and fun lessons in

math science programming data analysis
-
and AI And speaking of AI one might
-
think what's the point of even learning
-
these basic math skills then we have
-
Chad Gypt who can spit even complicated
-
answers to us However to that my answer
-
is how are you going to know if the
-
answer you got from Chad GPT actually
-
makes sense and then what's the point of
-
view if you cannot distinguish sense
-
from nonsense So Brilliant helps to
-
build your critical thinking through
-
problem solving and not memorizing which

is way more effective than simply
-
watching lectures It has nicely
-
structured courses crafted by worldclass
