I'm looking for a sail to blast around with in every-day conditions on freeride and and freerace boards: Currently a Tabou3S 96 and an oldish Tabou Rocket 115, but might change to something like a Goya Bolt 105.
I don't like the hassle of cammed sails and am not quite sure if I can really efficiently use their potential, especially without a dedicated slalom board.
I'm not in it to win it, but annoying a few people on more professional gear in the local speed challenge would be greatly rewarding

so I've set my eyes on the Koyote, which seems to have a reputation of going fast. Plus, it looks great!

German Windsurfing magazine have so far agreed on the AC-X being the fastest thing out there. I could buy it locally.
Has anyone ever tested the two against each other?
Or do you have any other experience with either of them to help me decide?
Any advice would be strongly appreciated!
