Just from my experience, PHRF MA does not penalize you for carrying sails outside the allowed one design rating. BUT-having non class legal sails exposes the boat to a ratings appeal, since the limitations placed by one design rules are part of why the rating is set as it is.
I am in favor of adding the 1/2 oz to the mix-we get a fair amount of light air in NJ (especially during our competitive Wednesday night series), and having a little more horsepower in the light stuff would be nice. And in one design, we already have decisions to make on sail selection with the 1 vs. the 3 (and for some, the 2)-I don't see a problem in allowing some sail selection choice on the downwinds as well. And light air would be a bit more fun...
