Has anyone used their synthetic line before? I emailed them and was told it is made out of UHMPE - same stuff Dyneema brand line is made from, which is what viking, winch line, etc use. But I know this stuff may vary depending upon who makes it. They've got good prices and sell the safety thimble made by a prominent member of other forums for those of you who know about that. So I'd trust that he wouldn't attach his product to crappy synthetic rope, but just wanted to see if anyone has personal experience with it.
