Tell them the lane conditions have changed...while I'm not an oldtimer, I'm only 33, I got started with a hard rubber ball, had it breaking 15-20 boards as needed, and carried a solid 180 average with it. However, as balls got better, they started putting more oil down on the lanes, and the ball became nothing but a straight ball due to the changing conditions. I'm sure you've had the experience of getting those plastic balls (house balls) to hook. Unless you go max revs with limited speed, you are totally SOL on the current standard shot.
If the lanes are right, 2nd shift in a hot house, I can pull out a plastic and still shoot 220's with it, but I rarely see the lanes dry enough to go that route.
