Its going to be hard to put this genie back in the bottle, way too many marginal bowlers have had the taste of big scores and big averages and have developed bigger egos and for them to give this up will be a monumental task if not impossible.  How many of these house hacks with 210+ averages would continue bowling if all of a sudden they found themselves averaging 170 to 190 where most of them belong. I know many want to blame the proprietor, some are maybe too blame and some may have little choice, and I doubt it has anything to do with a proprietor not wanting to spend money on oil, give me a break. I hate the high scoring environment, I've never seen so many 220, 230 and even a 240 ave. as I have this past year(bowlers coming to this house for a tournament) and listening to them talk you know there is no way many of them will want to give up these averages.
Personally speaking I place some of the blame on the old ABC, for not standing up to the ball manufacturers and placing more stingent guidelines on ball construction, the balls just keep getting better and better and creating higher and higher scores, balls that are mid performance today are equal or better than the high performance balls of just a few years ago and the scores just keep going up.  As the averages keep going up there is less and less upside to bowling and lot more downside.  I don't have any answers to solve the problem, I wish I did, it will take years and a lot of re-educating the bowlers to the benefits of a more challenging scoring environment in order to save bowling for the future.  I'm sure many of us played Candy Land, Hooks and Ladders, Go Fish when we where children, we don't play those games any more because they were too simple and didn't offer a challenge, maybe that analogy is a bit extreme, but if  all involved in bowling don't join together to make bowling a true sport, it may just go the way of those children's games.  Just another opinion..
