The glider factories seem to think that glider buyers are like Ferrari
buyers, who will accept to pay any price for their toys.

Nope. Why do you think some mfgs are still using lower-cost
(and lower quality) bearings ? Not using stainless cables ?
I have been told, when I specifically asked, that cost control
was the reason. The factories constantly look for ways to
reduce costs.

A primary cost driver is the FAI class definition, which sets
the market. And when there are too many classes, it just
runs up the per-unit costs. And no, it doesn't get hugely
cheaper when you cut the span...

My two cents anyway,
