I wouldnt reccomend fujatives for 70% all mtn. I own the 03-04 red fujatives (center mounted), and there horrible for any type of all mtn skiing. There too soft and flexy. You might be able to pull it off without center mounting them, but I still wouldnt reccomend it. Theres a certain speed that I know will cause the skis to chatter extremely bad, and I can almost call that speed. I dont even use them at the ski area any more. If your even a slightly aggressive all mtn skier, I would not reccomend you buying the fujaives.
If you do buy the foil, or a ski with a similar stiffness, I dont think you'll be dissapointed. The stiffer the ski, the more stable it is. I even ride stiff skis in the park because I know if I go for a 180 over a 35 ft booter on my fujatives, I'll probably die just trying to ride away switch because of the chatter. I also think stiffer skis can pop better. You just have to work a little bit more. I will reccomend you buying the ninthward butterlicous. I've never skied it, so I think you should try to demo it fitst.
