Guistware, Its my personal opinion that people are spending WAY too much time worrying about things like this. If a 70 inch plane at 28 oz per foot flies great, at 32 oz per foot it will still fly great and probably at 35. It may not make as square a corner or bleed speed as fast on the down line but, there are probably 75 members in the club that I fly with and if four could tell the difference I'd be surprised. Playing with them is fun, talking about them is fun, but as you have seen for your self, its not worth loosing sleep over.
