I was so happy to find this thread. I can not keep all three fingers down; my fingers just won't stretch that far. I think I have been playing too much period. My hands and fingers, wrist, and my forearm are all hurting. Having had a battle with severe tendonitis last year from too much playing my ukulele I recognize the signs and know I have to rest it. I'm going to take these suggestions in a few days and see if I can do spider legs that way.
