George,
You are getting a lot of feedback on this. I think that right hand technique is really a major factor to playing well. I've been shown a lot of excercizes over the years which I am sure all can have value if you stick to them (which I have not). But the main thing I'd like to pipe in here about is that if you study the great players, they all have pretty different ways to achieve great results. Some with more elbow, others, more wrist, and still others more finger movement (on the hand holding the pick). Some, like David Grier float a lot w/o anchoring their finger and still others are anchored like they have glue on their pinky. Some brush the bridge as a depth guage and others are dead against that. And, let's not even talk about how to hold the pick! The conclusion that I've come to is that we are all wired differently and what works for Tony Rice would be absolutely wrong for Doc Watson. So, you watch the great ones, but ultimately have to figure out what works for you. Not an easy task...but that's what all the good ones wind up doing. My 2 cents...
