I think a much better solution is to put an eye strap at the base of the mast and then use a 2:1 purchase with a becket for the downhaul. This keeps you from having to ease/tighten the foreguy when you are adjusting the guy since the pivot point moves to the base of the mast not the deck. One less thing to do when going fast down wind.
To do this you need to get rid of the bridle and lash D rings to the center of the pole. Most carbon poles come this way.
This is the system we use on the Laser 28 I race on and have been considering a switch on Natural High. It does work with a bridle though.
