The fix is already there if we want to take it: Cut down the oil. I'd wager most houses are already on synthetics or headed that way, so the issue of protection of surface isn't what it used to be.
Hardest shot to bowl on is a bone-dry shot. Next to that is a flooded shot. We could actually fix this by oiling the entire length of the lane but that puts too much oil in the machines themselves and triggers breakdowns.
Resin stays, core technology stays. In fact, loosen the core specs. Don't try to limit technology so much.
Don't touch the pins, because of the issue for juniors, seniors and other low-average bowlers.
Instead, use technology at the lane conditioning level. Drop the volume, then deal with the ratios. You'll still have times where you catch a "sweet spot" as the lanes are breaking down but it will be pretty short-lived. Take away the drastic walls.
And, EDUCATE league bowlers on the difference in oil patterns. Many, if not most, have no clue unless they've ever sought that information out.
