I wanted to come around the ball more and lower my track also, what I did was go from reverse pitch (5/16) to zero, of course I had to change my finger pitches to accommodate the thumb. While I do not disagree with the first reply totally, a change in pitches can help aid you in coming around the ball. People will ask why so for one, it helps to keep from squeezing the ball and a relaxed hand is a happy hand. Also, my thumb stays in the ball just little longer allowing me stay in the ball and able to get around it. Now I am not saying this is the cure all but it worked for me and sometimes it is worth the try. I am believe too many people have reverse for no reason at all. Like I read somewhere before, unless you have the span of Kareem Abdul Jabbar you probably do not need reverse. I also lengthened my span with these changes.
Now I do not know your pitches but sometimes change is good
