Oh Wow! I love guys with a super positive attitude! It is.... Inspiring! Isn't it Def Lepard that has a single arm drummer as well? I'm not sure, but I think he played without prosthetics and play a lot of double-base.
I tried the playing with one arm deal, my problem is I am right handed and my right hand is the injured one. I was trying one handed with my nondominate hand. Makes it a little tougher. If I still had my dominate hand I could still play pretty good.
