Thanks alot for the advice, it's hard to get much coaching in my current location, but I will look into it.
As far as the sprain happening before, it's not likely it's a pretty unique sprain. I just purchased the turbo diesel, and I will have the Proshops guy double check my span, I would hate to stop using hammer balls, they are awesome, but I have to quite bowling for atleast 2 weeks when this happens or it gets worst.
Again thanks I really appreciate the replies.
