Yeah I saw him before the pciking is indeed impressive (anyway thanks for sharing it). And it’s a neat idea to design a personal pick, I can imagine that one day we all print our individual picks perfectly matched to body and technique
Wrist is my standard motion too, the motion i meant is a mix, the repetetion is elbow but the ‘endpoint’ is the wrist. So it looks as if the wrist is doing the work but in fact it’s totally relaxed and free to do some ‘finetuning’ like slant or angle. My impression is that the relaxed wrist causes better feedback and makes the thing feel less strange.
With some luck I’ve a free sunday, I’ll try to ut something together then.
