I shoot a TTF side shooter catty, was designed and made by Bill Hayes, all of the forks are on show but never had a fork hit or handslap, I think "fork hits" are down to user error and are really common when people first start shooting catties, more than likely down to the type of catapult they are starting with rather than how they are holding it, takes a while to find a design you are comfortable with along with finding an anchor point that you are consistent with, just my opinion
