Agree with paulk on sail shape. I also have a fully battened main and would advise that you pay careful attention to the batten retention technique. My preference--after a warranty issue with North Sails--is to insert the battens from the luff end and have the batten pocket closed at the leech.
My first main had a double overlap velcro flap scheme at the luff, which worked pretty well. I replaced that with a new North sail that had a single velcro flap retention scheme at the leech end. It did not retain the battens so North subsequently closed the batten pockets at the leech and provided a clamshell device at the luff, which also allows for adjusting the compression load. It has worked like a charm.
Another caveat: The fully length battens tend to provide a slight projection--or at least a hard spot--at the leech and can catch lazy jacks when raising thesail--if you haven't pulled the lazy jacks forward.
