Beachboy, If you checked out the H17 forum, I show some pictures of the new PENTEX square top I got for my H17Sport. Pentex is a plastic like sail with criscrossed reinforced filiments running through it (very strong, very low streach). I got mine through Whirlwind Sails @ ~ $1650.00 for the pentex SQ top and a dacron jib. The dacron rolls better on the furler. The sail construction quality is top notch. I've now had the new sails out in varying conditions (light wind up to 35 mph) and have found that they outperform the standard mylar sails. They seem to be more forgiving off wind in higher winds with the twist off effect and appear to point at least as well as the standard sails. On one high speed broad reach I buried the leeward hull in a 3 ft wave sending me from the aft end of the windward wing to the front crossbar, but I still avoided a capsize due in part to the twist off effect when I let go of the sheet (and the mad scramble to the back of the boat), it was a close one.
