The shape of my 130 with foam is bad enough when reefed down that I would
sure go with the foam. The size of the sail doesn't have that much to do
with the geometry of the sail shape.

I'm always astounded how well my boat sails with the working jib which has
great shape. I put a luff doubling on it this winter so I can leave it up
and fly it more often. Good shape trumps area in most conditions.
