I find if you open the cam all the way up and regulate your descent like using an atc or an 8 with palm pressure and pull angle that it is super fast and smooth. For sure the first ten or so descents were jerky for me but once you get the hang of it, which is fast when you use it to lower other people rock climbing frequently, you apply that to lowering yourself and bam, PERFECT!

I have to disagree.
Gri Gri is not a descending device, and Petzl does not market it as such. It is described as suitable for lowering a lead climber, which is similar to rappelling for sure, but there are restrictions on distance and weight that would render it an unwise choice in what I call long descents...maybe not for your definition of long
, but be aware that there is risk of overheating the device enough to damage a rope if you exceed them.Additionally, the suitable rope diameter for the Gri Gri is very narrow, and is smaller than most arb ropes...it works best on less than 11mm.
Far better tools for that job are available.

My definition of long is a full 60 m rope length, and the application i used it most in was simul-rapping with a partner. two 60m ropes tied together threaded through the anchors, one climber weighting each side and rappelling off together. With the risk of one climber screwing up and killing the other the grigri provides a great safety net.
I dont disagree that there may be better tools, but, i still like my grigri, and i always will...
As far as the fact that Petzl does not market the GriGri as a descender, i respectfully disagree:

Descending
• Descending on one strand of rope • Descending on one strand with additional braking • Tying off the GRIGRI to have your hands free • Lowering with the GRIGRI on the harness, using a directional • Lowering from a fixed anchor-point • Self-lowering
-------------
From the petzl page http://www.petzl.com/en/outdoor/belay-devices/grigri 3rd bullet point...
The GRIGRI 2 has a new design that allows excellent control during the descent. One hand holds the rope and the other uses the handle to unlock the cam. The patented handle design allows a very gradual release of the rope. In combination with the strong braking action of the cam, it gives a great feeling of control when lowering a partner or rappelling.

The grigri is listed under the category: Belay devices, descenders
note: there is a seperate category labeled only 'descenders' implying that the grigri as well as the other devices listed qualify as both types of device.

Well argued, sir.
I read the full technical notice for the Gri Gri 2 and found no reference to use as a rappel device. I now see the line you reference in section 4.
http://www.petzl.com/files/all/technical-notice/Sport/D14-GRIGRI2.pdf
Does the 2 still have the same restrictions for distance and weight that the original model carried? I don't see them in the link I posted...I should look through yours. As I recall, it was limited to a 50 meter drop.

tas far as the technical notice, here is a small reference in section 4 regarding rope thickness, and again in figure 6 it says descender. The real proof in the pudding is in the first link i posted http://www.petzl.com/files/all/produ...GRI 2_EN.pdf pages 14-19
Why does petzl seem to provide different info in different places? I cant explain that but i can tell you this...
I saw that movie, "the darkest hour' about aliens, kinda like independence day, anyways at the very end there is a radio broadcast saying that a french militia took down one of the alien bases drilling things. It was a way to signify the beginning of the revolution, whatever.. You know the most unbelievable thing about the whole movie? Not the invisible aliens... The french militia! The idea that they would fight back kills me. Ever since the american revolution the french have never done anything but surrender. Maybe it is that fear of confrontation and liability that causes Petzl to be so mysterious?

Ever heard of the Napoleonic wars?
The French only managed to conquor most of Europe.
Quite the surrender.
