There isn't an average at which one should should buy more than one ball. You have to think of it in terms of skill. I say someone should buy more than one when they are actually good enough to have a use for more than one. That isn't dependant on average, because I know bowlers who average 190 soley by making all their spares, but their strike game leaves a lot to be desired, and if they had multiple balls they wouldn't know what to do with them.
Then there are people like me who are inconsistant spare shooters, but their strike shots are refined enough that they can't get by using a single ball for several games because lane play becomes a big factor. But I think that with either of these types, coaching/practice would be worth more than 1000 bowling balls. Bob "I make all my spares but get 3 strikes a game" Smith would see an improvement in his strike game with a coach and then could start to take advantage of all the balls on the market, whereas people like me, Tom "Get 8 strikes in a game and shoot 220" would greatly benefit from a coach to improve spares (consistency, which would help the strike game incidentally).
Compare me and one of my team mates, for example. In a tournament (with qualifying, match play and the works), I would be more likely to win a tournament because if my spare game was on track, I'd be likely to average 220 for the day and have a few runs at 279, 290 or 300. On off-spare days and days I didn't have a secure line, however, I'd be well out of the cut. But my friend would make the cut (and likely cash) more often than I, because he'd make his spares and get the same amount of strikes regardless of the condition. So he would rarely use more than 2 balls per 5-8 games as it wouldn't help him, and he'd rarely change his release, whereas I'd be constantly fiddling with my release and change balls. But like I said, both of us would find a far greater advantage to get coaching.
