Just bowled my first league set as a lefty last night. I have something going on in my left hip where I can barely make it through a set right handed. Without getting it checked out, I'm guessing it is a soft tissue injury around the joint. Anyway, I bowled pain free! For those of you that have switched hands, any tips on the change over? I got a 14 lb rocket drilled left a few years ago and have already bowled a bit lefty, but nothing serious.
