you don't need a track for the outhaul. Make sure the boom is cut several inches longer than the foot of your main (measured with the main flat on the floor obviously). Put an exit block (harken part 242 or similar) at the end of the boom and rig a 2:1 block system in the boom to use as an outhaul. Gets a little complicated trying to explain the 2:1 set up but still a better idea than a track.
