Rack, Charlest is 110% correct in suggestions. Only comment is, change only one thing at a time to narrow down the trial and error process. You can change your finger pitches easily to reverse pitch (try 1/4 away from where you are now) and usually it does the trick(if you haven't done too much damage). The reverse pitch on the fingers place your hand in a position that does not require as much hand rotation to release the ball, so you are able to physically release sooner with your fingers then with forward pitch. If the span feels funny after that, then change the span per Char's recommendations to get the right feel. Keep trying until you get a good feel, but it's always easiest to know whether you like or dislike a change when it's an isolated situation. Good luck and hope this helps...feel free to contact me directly if you need further assistance.
