you may have also considered such details as no hand >twisting, no finger twisting and limiting finger side-to->side motions to joint 1. Not exactly sure what you mean by no hand twisting. But if you are refering to hand-wrist twisting then no there isn't. The way that the parent is prevents this. The forearm twists but not the wrist. Though you could easily twist the wrist if you used a different controller. Constraints don't permit finger twisting. Joint 1? Do you mean the index finger? I had limited side-to-side constraints set up for all the fingers, since fingers generally have a limited amount of motion, but was forced to change this because it was causing issues with rotation. A small detail that shouldn't be noticed when animating, and if necessary you could enable the side-to-side ability you'd just have to be careful with the movements. The point of this setup was for quick and easy manipulation with a good deal of control of the mesh being deformed.
