try and remember when urethane balls first came out. they had a pancake weight block---it really didn't matter how you drilled one, the improvement came in the form of the added traction from the coverstock. the best bowler would win. the first reactive ball had a pancake weight block. again, the real improvement came from the coverstock. the person who bowled the best won. as technology in bowling balls has advanced it still boils down to who threw the ball the best. matching up to the lane surface with the right surface on the coverstock. i'd much rather have a ball with the "right" surface and the "wrong" drilling than a ball with the "right" drilling and the "wrong" surface.
