Hi, is the bottom half like a silver blue colour and the top black? If yes its prob 04/05. I think yours is an 04/04 460. Luckily, all the Viper races have the same bend curve so the year of the mast wont matter. The Norths do set pretty flat at the bottom 2 panels. Despite this, the Warps still have alot of "grunt". The power comes from further back in the sail. Also, when the sail is powere up, you will notice that the sail developes a bit draft. You can put a couple of cam spacers in the bottom two cams and wack on the batton tension, this will give you extra power and stability, but cams will need a good kick to rotate. I've had the F2004 through to the F2008 and they'v all had the flat shape. Dont be fooled by there flat profile, as they are definitly very grunty.

P.S. The F2007 likes to be set at max downhaul (on the VTS), power can be altere via the outhaul. Cams will seem stuborn on the beach, but once powered up on the water they rotate OK-ish.
