Bob - so who is Beebop's latest sailmaker that requires the retune? What do you see different on the cut?

On Rhapsody, I've got max class headstay, mast base 1" from step and the "every day" sails as Quantum Main & Jib. The tune that works for them has the uppers tighter than the lowers. The "new sails" are North. I've played with different setups and last weekend raced with equal settings 1000# upper & lowers with light air predicted. The boat seemed to move ok, but as the wind picked up from 8 kts to 18 kts (not per prediction...), I didn't like the shape of the main. The luff was real baggy and the leach looked tight. Almost like the sail was cut fuller towards the mast. Any pointers for settings people like with North Sails?
