I don't think the part about Gri Gris came from Craig. Craig has written about proper grigri usage in his beginner's guide. I have probably belayed Craig on my grigri (given the weight differential!).
There are times and places for grigris, ATCs, etc (even the munter hitch. . . )and room for personal preferences. No device is an excuse for sloppiness, laziness or inattention. Of course, you should learn to use any gear you buy!
I have never dropped a climber (grigri or ATC or butt-belaying), but I have been dropped by a belayer with an ATC. I do not blame the ATC. Most of you I have belayed with a grigri
A dynamic belay can be a good thing-- putting less tension on the rope and the climber. Dropping someone an extra few feet purposely to avoid a bulge or flake can prevent greater injury (as sometimes can taking in extra rope). . . I won't try either of these with an ATC, where if someone falls, I want to break them off! . . . try to break them mid-fall and you could get nasty rope burn on your hands, making it even harder to stop the rope.
We should start a new thread for belay devices. . . or someone want to nominate another piece of gear for discussion? I just (finally!) washed my rope last week, so I was just checking rope pages to remind myself if it was warm or cold water (cold). . . but always good to refresh/update your knowledge, especially as gear and climbing continue to evolve!
