I (and others) have posted multiple times in the past on 5.0 sailing/tunig/rigging tips- I suggest you try the search engine for the forums (especially the old "original" one) as a start-

If you can't find anything E-me personally or repost and I'll try to help you out. I owned #1030 for 17 years (and ordered the first set of "racing" sails for one) so know a little about them-
