I don't buy it either.
The ezloc rudders can be updated to accomodate the EPOs (kind of a pain in the butt, but Jeremy proved it can be done) and there is nothing written anywhere that says you can't match the arm lenght to that of the original rudders.
I just don't understand the negativity toward the HCA-NA from this guy, when we've done nothing but try like hell to be as accomodating at our events (regarding equipment) as we possibly can. Even totally ignoring our written rules for the MWE events in florida. And as far as meaningful Wave sailing goes, we had 12 boats at the mini mega. NOt alot of the HCA racers (16s, 20s etc....) are very big fans of the wave so I was pretty happy to get that many.
