The way we did it was tying the ends together with some "fishermans knots" on the trampoline and leave the sheet on the boat (mast up storage). Sheet had a pigtail in the middle of it made out of 4mm spectra, which we tied to the spi with a bowline knot. It was what the rest of the fleet also did. Works really well. Less weight at the clew in light winds, easier to jibe in my opinion and also cleaner.
