Shopping for new sails for a 2004 323 with in-mast furling. I have two questions: (1) can I put a main with vertical battens on this (older) boat? If yes, any pluses and minuses for these sails when compared to mains without battens (I now have the latter)? (2) I have contacted a number of the major sail makers for quotes and I have discovered that each quote is unique in one way or another and this makes comparing them somewhat difficult. Any suggestions that might help me choose a source for my sails (the boat's current sails are Neil Pryde). Thanks!
