Eric,
On Flight Risk I've got a vectran line run between the main beam and rear beam, with a loop tied in it where the turning block is located. It can be adjusted to move the sheeting point fore or aft.

And if you rig the line below the trampoline and pull the loop out via one of the existing grommet, you have the perfect setup: at the right place, and it cannot tear your trampoline.
