I am 145lbs, 5'8", and sailing Laser Radials. My current racing sail has gotten soft so I need a new one for a string of regatta's this summer (ACC's, NA's, Youth Champs, and Men's and Youth Worlds). I know that the Euro sail lasts longer in general than the North American but I have also heard that one of the sails has a slightly flatter cut then the other. Is this true?
