I reran my tweakers (twings) late last year and love the setup. I have a small block on the aft side of each of the middle stanchion bases. The line runs from there to a bullseye fairlead just forward of the genoa track and to a cam cleat/fairlead combo on the cabin sides, near the top and about 1/2" from the back. It works great and is within easy reach of the main and jib/spin trimmers, pit, the middle of the boat railmeat and even the driver.
This is a major improvement from the way I was running them, which is through a block and cam on the stanchion. I can get some photos if there's an interest.
