USBC is in a bind. If they do anything to tick off the membership, they'll cease to exist. And with the BPAA waiting in the wings with their "Contemporary Bowling Association" they have to be careful what they do and who they infuriate.
Removing the double void in the bowling pin is certainly one way to keep scoring down. Pins are replaced every couple of years, and to design something that's more difficult to topple and PROVE it might take a few years before that. To me, that's one answer. Another would be to gradually increase the lane oil ratios on the outside boards. The reality is, however, centers don't want decreased scoring and it's not likely without going back to the days of certifying an honor score AFTER it's thrown that USBC would know if one pattern was approved and another put out on league night. But saying USBC could get enough members on board, perhaps the 3 unit rule could be increased to 5 next year, to 10 the next, and then close in on a 5:1 ratio (roughly double the 2.5:1 most sport leagues have to endure now). I can't see the "average" league wanting to bowl "S"port every week because it isn't fun, it causes migraines, and face it, some people would never have the concentration for it. But that's not to say that USBC has to decide whether they're going down with the ship trying to right it, or if they're only going to continue to make things worse by offering bad (and costly) solutions and proving they have no idea what the average bowler (or even the elite bowler) wants from the sport.
