I understand the costs of oiling the lanes and have seen costs of cleaner and oil lately (not the duster cloth). And I would love to see what one center says is the cost per lane and a breakdown of such. Is it pennies? Of course not. But you can't tell me it costs much more than $1 a lane (not counting labor, but the mechanic is already there anyway).
And the reason I say it is up to the local GM is because not all AMF centers are doing the same thing. Just because one center isn't oiling doesn't mean they all aren't. Each GM has an operating cost he is trying to stay under. By cutting costs any way he can he may incur a small bonus for himself. I am guessing this GM isn't a bowler or doesn't operate the center like a bowler might.
I have managed bowling centers before and have worked for AMF before the merger. Yes, there are a lot of idiotic rules at AMF, but there is no rule for AMF centers to not oil the lanes on the weekends. It is the decision of the GM to not oil.
My center had college teams coming in for a tournament a few weeks back.
The team that was coming in has a specific shot that gets put out for them.
The person who was oiling (Who can get pretty lazy at times), decided he didn't feel like oiling the lanes twice, so he put the college teams shot down. In the morning. Before 2 leagues bowled on them.
So, not only did my league have to deal with a pattern thats not at all what we're used to, but the tournament played on burned up lanes at the end of the day.
Doesn't surprise me that another center doesn't oil on weekends after seeing what ours does at times.
As for the original post, whats wrong with your spare ball?
Have you actually tried it on those conditions? I would do that first before buying anything new, just for the hell of it.
