Bear with me here. Wondering if the mods have ever looked into this idea. I’ve got a brilliant drummer friend who talks about the energy he can save in some situations by letting the stick rebound (“rebound” as a noun) off of the drum heads assist his lift post-strike and help him into his next move.
Which gets me thinking if there’s part of the wrist-extension portion of your movement that can receive an assist from the kickback the string might give you post-swipe. I was just watching “Crosspicking With The Wrist”, and I guess this would be the “2” portion of the 9-0-2 pattern after the downstroke, or the “10” portion of the 10-0-3 pattern after the upstroke. Not to “launch” you into space, but maybe help relieve some of the effort you expend on the lift. Hope this makes sense!
