Pentex is 1.8 times stronger than polyester. The one-sided film on the windsurfing cloth(polyester fibers) is less resistant to stretch than it's polyester conterpart in the two-sided film line. Put pentex fibers inside and you have an even stronger sail. If the other classes are going towards square heads than it would only make the 17 perform better.
