The Petzl GRIGRI is rated for use on 10-11mm rope. Anyone have experience, pro or con, with using a GRIGRI on 13mm (1/2") rope?

How is descending on a Gri Gri? I've heard it can be rather jerky (?)
Anything over 11mm is like stuffing a sausage into the Grigri. Even New England Ropes Fly (allegedly 11mm) has to squeeze though a Grigri. Tachyon (Lava) is a tight squeeze though a Grigri, it works but is not great. I'm talking about SRT descent not for lanyard use.

Yeah, I was fairly sure what kind of answer I would get. I really like the GriGri concept but got big hands and all my ropes are 13mm. I checked out the large "I'd" - it's huge and cost twice as much. The spiderjack is three times as much. Then there's the unicender at $450.
Still looking for best single mechanical device that will do it all - ascend, descend, & limb walk - probably doesn't exist yet.

I have had a gre-gre for about 10 years and it works fine with 1/2 new england Hy Vee and safety blue, we use it for belay in our Spikes training , less mistakes than with a figure 8. some of our job corps students are not to tightly wraped
The Gri-Gri? That's that little blue thingy with the red handle and some wheely things inside? I knew a guy who would stuff his 16 strand in there and hang off it. He said " It just fits".
Now I was over at the Plasman's place the other day and I think he was showing me that ID thing. HOLY CRAP! Its plastic, that's gonna break. You can expect to do real work with that thing. Hey, it might work just fine doing what it does and it does but that thing ain't gonna take no abuse. I find it kinda scary, I mean these are things that you are supposed to be able to climb MT Everest with right?
I was just climbing SRT last night on Tachyon and it worked with the Grigri for rappel but it's kind of tight. Not surprised, it's thicker then Petzl's max rope spec of 11mm for the Grigri.
I don't like the I'D because it's too big but all the parts engaging the rope are metal. The little plastic "safety" that allows you to take the biner off the I'D without disengaging the rope must be what you're referring to. I've never heard a report of that breaking. If it did you'd stay on the rope anyway. It's a good piece of gear.

Also it looks like you have a big clock hanging from yer neck like that rapper dude.
