I've been using Tortex III picks for about 9 years now, first starting out on 0.88s and then transitioning to 1.00s.
Pretty much the only gripe I have about these picks, is the durability... but that can be justified in that I have a heavy picking hand. As I like having the tip as sharp as possible, I generally go through one of these in a week or so, or after about two rehearsals, whichever comes first.
Other than that, the grip is good and the tip of the pick is sharp enough to have a precise attack, but round enough to slide nicely along the strings - thus, a great middle ground between a regular pick and the Tortex Sharp picks.
