I bowl in a Monday morning league with very low cost linage, yet the areas of concern for league health seem to be the side action and the end of year payout. What the majority of the league does not seem to realize (or they do, but it doesn't click) is that only the top two or three teams (out of 16) are the only ones who come close to making all their money back, plus a little. Also, side action has seen a slow, but steady decrease, during the past three seasons.
The idea I bring up every year in the league meeting (which is laughed at and shot down) is that we should drop the cost of the league to just cover linage and secretary/treasurer's pay. For example, say we paid $21/week to bowl (no side action included) and of that $8 was to bowl and $0.50 was for sec/treas. My suggestion is to drop the weekly fees from $21 to $10. For a 33 week season, that is a savings of $363 a season for each bowler and more than 75% of the league would recoup at year's end. But, that "money at year's end" stigma is the way it's been done "forever" and there's no need to change (that's what I hear).
Now, my contention is that with lower weekly costs, it could be easier to advertise the league, the league could have a higher competition to cost ratio, and more bowlers could get into the side action pots. These advantages might not pan out, but an attempt should at least be made. They won't even try it for a half-season and see if the lower cost benefits pan out.
I just like to bowl for the fun, beer, friends, and competition. That combination seems to be in the majority for this area.
