In reply to billy no-mates:
Don´t understand this myself, Petzl say they are stopping the original Grigri which is going to cause problems all round, my local wall use 10.5´s and have ordered all they can get hold of for this very reason.
For bolting routes setting and dogging projects where normally you want a 10+ rope and probably it wants to be fairly robust as well then you also have a problem.
I´ve done pull tests on the new one and even with normal, good condition 10mm I still had to hold down hard against locking-up when testing the feeding resistance and found it far too grabby to be useful.
Great for 9mm but nothing for 10mm.
Useless for lead roped soloing even at my snail-like pace, feeds o.k. for top-rope soloing. Used as a bottom jumar on the harness the rope tends to drop under the handle, nasty.
