I have no experience with Dynalite. Only thing I heard was that some sailmakers charged a premium for working with that cloth <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" />

(You should know, I am no pro sailmaker, just trying to learn as much as possible about how to make cats go fast. Sailmaking is part of that. Normally I work with computers and system administration)
