Russ-the problem is that in some PHRF districts, we are required to use only class legal sails in order to maintain our one design based rating-so carrying a 1/2 oz. is not an option (nor is an aramid main). It seems to me that if you time your sail purchases so that a new 1/2 oz. is delivered just before the NA's, you could then "retire" that chute into your PHRF inventory. That would save the cost of duplication.
FYI-my general strategy is to get whatever new sails I can afford just before the NA's, and then I use that inventory for the next season's PHRF sailing (although I've been sailing with the same sails for the last three PHRF seasons and the last two NA's that I attended).
