I think the mechanical devices are more for the bigger guys, they just get in my way. The pantin is cool when I am beat, but would rather just go on my own. I agree with Beasty, master foot locking and hip thrusting, then when ya show on a job and forgot......whatever little device, it doesn't send ya back to the shop. I use a swabish (sp?) prussik, I hip thrust and use the foot look to belay my line. My climber only climbed with gaffs when I got him (I have converted him from the darkside) Taught him how to foot lock, now he prefers it, even when he can wear gaffs, he dont, would rather go straight into space, and he is damn fast too, faster than I ever was. I have a bunch of the new, cool and hi-tech little devices, but to be honest, it is just more to get in the way. I just put my gri gri back in the shop, rather use the ol 2in1.
