I'm not saying that wings would save money, but there are probably only a very few (I would say literally a handful of) people on this forum that know how expensive it is to keep up with sail costs for typical Olympic classes (Tornado excluded).
When I first met Bob Merrick, he told me that sails (especially jibs) were only good for one regatta. This was shortly after he won Silver in AUS.
Being the (relatively) cheap H16 sailor that I am, I was totally unable to process this thought, but apparently it has (at least perceived) merit.
BTW, Mark, please try to keep your rants to 4 paragraphs or fewer, you lose me (quickly) after that...
