Stupid seven Pin....

The easiest thing to do, is to add some pitch in the direction you are feeling the rub. Left lateral or right lateral. If you use thumb slugs this is easy. I will tell you first, I am right handed. My teammate was having the same problem with swelling but he did squeeze the ball. He had a slug in his thumb hole and said it was slick and hard to hold on to. He is left handed but I do not know his pitches. I gave him a cork to use in the front of his ball. This gives him a consistent feel in all of his equipment now. Your problem could be totally different than his. Without looking at your ball or watching bowl you it is kind of a guessing game at this point.
