Wow Jay - thanks for asking this question prompting these great responses; especially Christopher's suggestions. I'll be digging into that.

My Bluegrass flat picking friends- and these guys are smoking fast alternative pickers - talk quite a bit about the mechanics of it. Each of them discovered their own mix of finding the right anchor, elbow, wrist, angle of attack, etc. Also things like beginning on an upstroke or downstroke?

They reassure me that the more I do it, the more my body will naturally adapt and find the right combo that works for me. If I genuinely hit a limit, I'll try a deliberate minor change. My last minor change was a very slight adjustment where I was anchoring. Amazingly enough An immediate result was that I stopped dropping my pick as often as before. Go figure. [br]I-feel-really-slow!

But I'm working on it
