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.

I've got some 1/8" spectra left over from a dicked up set of trap lines I'll try out. The lace on the rear bar definetly needs to be changed out to something more slippery. Actually, this might be tomorrow's project.
