I just bought a new tarp (from wilderness logic and its awesome btw). I plan on making my continuous ridge line out of zing-it, but it seems silly to use something that expensive on the side tie outs. I am having a hard time finding braided polypropylene mason line: most is nylon. The closet I can find is from Home Depot and says "MAY contain polypropylene, and nylon" is twisted vise being braided. I guess my question is, does it really mater either way since I'll be putting the slingshot tensioners that Jeff has on his web page anyway?
