Barry,
I can't see how your poll offers any answers. I might answer that I prefer racing one design, but I still believe that the Box rule is a better solution for big fleets, because regardless of which brand you prefer, you can still compete boat-for-boat. In the end, I think you HAVE to have Portsmouth, so those with modified, or rare, or unique boats have the opportunity to race their boat. I didn't participate in the pole.
It might be interesting to ask if Portsmouth racing should be eliminated, forcing racers to fit into a limited number of choices.
