Re: new 120% genoa
The credits for smaller headsails are just that, credits not true rating adjustments based on real performance. The A33 has a SA/D of 20.3 which is pretty good. The determining factor should be the average wind conditions in your area. If the wind, on average, is 10 knots or less go with the 155%. If the wind averages higher than that go with the smaller headsail and get the credit. The sail prices you mentioned seem about right although there are some less expensive alternatives across the border. I got a 155% Twaron (Kevlar) for less than $2,000 made with Dimension Flex cloth. The sail was made in the US.
