As you know... but for the benefit of the post. I went from a centre sheet 6:1 system (Ronstan RF7) to a rear traveler 6:1 system (Harken 2613+8mm cleat) to 1. reduce weight (lost 835g) and 2. clear the deck for Mk2 and 3. The centre sheet system limits traveler use, (tightens leech, etc). Make things as simple as possible and you will have less liklehood of Murphy sticking his nose in when you least need it. <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" />
