Alrighty, so this is my takeaway from the discussion..
1) by and large, the reasons for bowling's decline in the U.S. have little if anything to do with the rise in scoring, but are the results of broader socioeconomic factors.
2) though most of we forum-lurking lane dwellers would like more of a challenge, most league bowlers would not be happy bowling on butt-clenchinly difficult patterns all the time.
3) without MAJOR fundage, enforcement of any tighter USBC regulations would be impossible, (although, perhaps this job creation could be subsidized? get a lobbyist to Washington folks!! joking of course
)
4) for the smaller percentage of dedicated bowlers, there are still avenues by which you can challenge yourself. <<< now HERE is where i will disagree, i think that casual bowlers have indeed supplanted the space where by more serious bowlers could get some game-time on the lanes, mostly because, for reasons already stated, they are more profitable.
EDIT: one thing i forgot to mention, i think we can all agree that the oil conditions, got easier and so to did the equipment get much stronger. I think part of the reason oil conditions are being talked about so much is because changing the equipment standards at this point would set ball manufacturers back quite a lot, though i'm sure they would dream up some new workaround quick (maybe they already have a contingency plan?). also, a whole lot of equipment would likely become illegal, which means those guys that have a whole rack 'a balls would need to go out and buy all new equipment. on the other hand, changing the oil pattern is as easy as just putting down a new pattern, it takes a few minutes and bam, game is different.
my creative solution to this problem (being the lack of challenging conditions to bowl on) has basically been to use a plastic ball and try to maintain my average. a few guys in my league practice with plastic very often, usually after the lanes have been blown to hell from cosmic bowling, just so they can be more accurate, and it works.
As for the state of the sport itself, i don't think tenpins will disappear altogether, but the fact is that it's not up to us, bowling just isn't that popular in this League of Legends/ Call of Duty/[insert videogame here] world of free digital entertainment. Sometimes you have to go out and create your own challenges. All we can do is remain dedicated and hope the changes in the wind bring favor our way.
whatever the USBC has cooked up for these surveys, we'll have to adapt and hope it doesn't hurt the sport.
