I think i got the motion going on one string, but the most trouble i have is with string tracking.
It messes up the consistency of motion for me and i sometime miss the target (target being the new string) when switching strings.
I wish i could train string tracking so it could go in steps (one step = one string shift) rather than moving my arm by random amount and hoping for the best.
What is the best way to do string tracking when crosspicking? Elbow extention or wrist deviation?
