Well, itīs the opposite for me, havenīt tried this big camsails. But I bought NCX after a test in Surf magazine, where they liked it since it was fast and could be sailed overpowered well. (If I remember right, they mentioned it didnīt loose anything against 2-cam sails in the strong wind segment.)
But you have to go to the shore and pull more downhaul when the wind starts to hammer, but then you can easily hold it without excess pull on your backhand. And when it is big I change down to my Severne Element2 6.5m2 (2-cam), and then eventually to Overdrive 5.5 which is a nice sail also on the Futura.
You probably loose some planning power in regards to cambersails, but I liked the fact that it should be lighter both in weight and handling power needed. Can surely be recommended if you are on a freeride board.
