Dead set . I mentioned this before but that facnor system is simply not a sensible solution on a single handed boat. It just sucks if you are trying to race.

To furl the spi you will find that you have to pul 4 or 5 times the amount of rope that you have to using a single line system. Believe me I've used it and it is far from the magic bullet you are after.

To furl nicely you need a very thick and very expensive piece of non twist rope to furl it round. I wouldn't want the Windage or the extra wieght. Think about what happens to the kite during the gybe. It will get wrapped around the rope and cause all manner of problems.

Most importantly for people that can't afford to replace the spi 3 times a year, then it definetly not an option. If you want to wreck a nylon sail as quickly as you can then furl it around a piece of rope while it flaps like a bitch because you can't get it furled quickley.

Like Bob said. Single line system. Cleat on the beam. Simple easy. Silicone it if you still have problems.
