it seems that you use traditional grip (left hand is upside down) while drumming. is that how you learned it?
i started matched, then in 4th grade in gym class a basketball hit me in the middle finger and temporarily jammed it so i couldn't bend it for about a week. that's when i realized that it's actually possible to use traditional grip without bending that finger. so i switched to traditional until the finger got better, and then i never switched back
