Can anyone suggest how I might improve my "floating fist" style flatpicking? I'm trying to clean up my pick technique for the sake of accuracy, feel, speed, and general ease-of-playing. I use the "floating fist" hand position a lot (hand and wrist floating freely, as opposed to anchored on the face, strings, or bridge of the guitar), but I can't play beyond a certain speed without resorting to some amount of anchoring, because the rebounding force from pushing the pick back and forth through the string starts to make my hand bounce out of control. Talking about single-note stuff, not chords...
I've been trying to address this by focusing on keeping my pick-strokes in a flat plane and keeping my grip loose enough so that my fingers will absorb some of the bounce before it creeps up into the hand and beyond. I've also been focusing on generating some of the picking force in the elbow, as it has to at least counteract the force of the string pushing back against the pick. I've been practicing alternate-picking on a single string, and at slow speeds I can keep it together and it feels pretty good. But again, past a certain speed the bounce creeps in and my hand starts to bounce off the strings.
Maybe some amount of anchoring is just unavoidable for playing fast runs, but I'd like be able to reduce my dependence on it.
