Gypsies, all the above are correct in what they said. Per Ray Edwards (Brunswick) and Mo Pinel (Morich) as of just last Tuesday at a seminar they stressed how the placement of the weight hole, location, depth, size all can fine tune the reaction of the ball, it can effect the space between each flare line, the width of the flare and how much it flares. I am not an expert but those two guys are. Hope this helps, good bowling.
