As Lance said, plus the sheet is lighter overall. Playing the main upwind is much easier with this system as it runs more easily.

You should aim to cleat on the non-tapered section. If you find yourself regularly cleating on the smaller section then your taper is too long or your strop is too long. Either way some adjustment is needed.
As I said earlier, my sheet is set up so that I can't quite get block-to-block and the thicker part of the sheet runs only through the ratchet and the cleat.
