After some thought and discussion of sail design change ideas I have decided that I'm 110% against allowing carbon top sections in the standard rig. Why? Well currently us, em , "heavier" folks currently get an upwind advantage in the heavier breeze and we get eat up by the lighter guys downhill. So, some of us get to enjoy better finishes when the breeze is up. With a carbon top section the heavy folks uphill advantage will go away and we will find ourselves in a lose/lose situation to those within the "competitive" weight range.
