It seems like the FAI list of club class gliders and their handicaps is simple and straight forward. Doesn't it make sense to adopt the FAI standard in reference to Club Class competition? The FAI won't allow an LS-8 (or similar glider) to compete in the Club Class Worlds, so why do we allow them on the US club class list?
