Interesting. This post made me analyse how I pick. I don't really play from the arm, more from my wrist. I could improve and clean that up a bit. I don't anchor anywhere, my hand just floats (I left hand mute when I play off of the bass strings), except when I palm mute then my palm rests bridge plate edge (52AV).Play more from the wrist and less from the arm. If you anchor, anchor on the high E. My hand barely goes outside of the string spacing.
The reason I keep hitting the switch is because my fingers stick out, particularly my ring finger. I think it's because of musscle tension, trying to concentrate on something makes me extend my fingers, seem more natural as well.
