I find I can strum much faster if my strumming arm is free of the body of the guitar. But is the curvature in my wrist that goes along with that bad? I also have problems keeping the guitar steady when I am sliding chords up and down with this... is keeping your arm free of the guitar okay, or is there intended to be some sort of anchor for your arms?
There's no proper rule for that, its all up to you to get the tone you want or the most comforting.
