Dave- The FXone has the same goofy setup as the Tiger. It is impossible to get the tramp tight. I was using 1/4" vectran, with a truckers hitch, then wrapping the triangle in the corners pulling them together. Not a real big deal, as it is pretty stiff even with the the tramp off, but I've grown to think that all tramps should be as tight as a H16 tramp too.
I hear you're making it out this way this summer! Whatcha bringin'?
Y'all need to go to tramp tightening school. 1/4" vectran is way big - 1/8" would work fine. You can run also stainless wire in there and terminate with a thimble just inside the tramp and then lace through the thimble. I do a 3:1 lacing and haul tight using a harness cross bar. That together with a couple of rounds of tightening on the rear (replacing the factory string with skinny 12 braid) and you can get the tramp tight.
