J/30 Class Association Forums J/30 Forum The Boat, Sails and Equipment Mainsail options 2014

I'm collecting quotes for new mains in various configurations:

1) Class Dacron
2) PHRF non-exotic
3) PHRF unrestricted (but budget conscious)

North is the first to respond, and has suggested a tri-radial cut from Nordac Radian 7.5

The sales guy says it will outlast/perform Pentex. Does anyone have experience with this?
