I made the mistake of buying a new 6.6 & now I have to sell my favorite sail, in good condition and likely to last another 5 years or so, they are so toughly built. Sets beautifully, goes fast and easy. The Slake sticker at the bottom covers a small crease that looked likely to split but needs no repair, otherwise its fine. reduced to $200.
Also a 7m TRX in good condition, no holes or patches; $300
