I think @horton is suggesting something that might get me to participate in a few tournaments each year. I can't stand 15off or skiing at 32mph, and don't consistently run 28off. That means a 22 opener and miss my 28off. Down and back. Last tournament I skied, I told the guy skiing after me to get his ski on, I'd be right back.
I think John's suggestion needs some refinement to make everyone happy. How about allowing skiers to run their opener twice as long as they don't fall, but then they are limited to 4 passes, even if they complete their last pass? Maybe not for and L or R, but at least allow this at a C.
I do agree that "opting down" is a silly suggestion.
