I see. I dont even know where mine is.I quit using it in favor of the ATC.

If you are truely worried about the rope slipping through a Gri, try the Trango Cinch. (http://www.trango.com/prod.php?id=102) It's designed for 9.4 to 11mm ropes.

well i'm trying to keep my gear purchases to a minimum.. otherwise i'd consider it more.

The gri gri locked up just fine, but I also had my right hand, of all places, on the brake rope. Once the gri gri has locked up and you begin to raise the brake rope up, you will feel it slipping, but only minimally. You aren't going to have a screamer rip the rope out of your hands and send your climber plummeting to the ground if that's what you are worried about.

that is what i'm worried about.. but it's good to hear that it won't fail to lock up. and my brake hand doesn't leave the rope when someone's climbing. i learned with an atc and have it pretty ingrained to never leave that hand go. when they're hanging, admittedly, i'll let go to do something like flake the rope or grab a sweater.. but even that's pretty rare.

I noticed this slipping last night at the gym. Scared me until I figured out what was happening. There were no issues when catching, only lowering.

Keep in mind that the listed 'rope diameter' is pretty vague for these purposes. There's a standard testing procedure for determining the outside diameter of the rope under a certain load. But what matters here is how well the grigri will 'grab' the rope, and that isn't just a matter of diameter, particularly when you're dealing with a really thin rope.

My sense is that we're still in the 'OK' range for using the grigri with these ropes, but pushing things. My concern is that the 'right' combination of rope, grigri and fall will cause the grigri to only partially grab the rope and the leader will take a whizzer to the ground. The only way to determine that 'right combination' would be with field testing, and I don't want to be the crash test dummy. It seems like it's time for Petlz to redesign the thing to deal with skinny ropes (after all, it will sell more of the things)

You want a rampage? The rrc.com 'debates' are nothing compared with the old-school flame fests on rec.climbing! Those were some 'rampages'! (Ah, the good old days of the Internet...)

I climb on a 9.4 Dominator and have taken some mighty plunges with no problems. The whole reason I went with this rope is that I climbed on a friends all last summer and loved the lightness, clipping, and ability to still lock up the Gri Gri. I'd say you should have no problems with a 9.6

One thing to keep in mind. Be very careful when using a heavily worn grigri and a thin line. Mind the break hand.
