Here we go again... balls and legitimacy of the sport.
... and anyone CAN go out and purchase any ball they want but everyone still b!tches about that too.
Whether you can afford too or not (with two kids, I'm in the not category - can swindle one ball a year on average) is irrelevant there is no restrictions on who can or can't purchase a ball on the market.
But I agree that both aspects have attributed to the decline in 'legitimacy' [don't like that term though, personally], aggressive ball technology and lane conditioning. A well laid sport condition can take the bite out of most balls (for a period) and turn a 210-220 average bowler, these days, into a 170-180 average bowler. So I do in essence agree with amagill.
Unfortunately the battle of the lane technology versus the ball technology is being won by the ball techs in every centre around Australia (it seems). Who to blame though? The centre's? Remember they are a business after all and if they make the conditions difficult bowlers walk. The Ball techs? They are a business also and they are in the business of making new balls to sell. The lane techs? They have oil for all conditions, it is up to the centres to lay it appropriately. or, the bowlers? what is their excuse again? Oh yeah I am a 210-220 average bowler!
Hmmmmm.
I do think clarification on the topic @ hand is needed though.
again only my $0.05
