I've only skied on the invaders so I can only comment on them. The skis are really a lot of fun for the park and messing around, but they're not a carving ski (but thats not what they're meant to be). You should have no problems skiing all over they're just not as stable as the stiffer skis. In the park they really allow you to do a lot of new stuff like butters, tails, etc. Buttering on them is pretty easy the ski doesn't really fight buttering like stiffer skis do (publics enemies, etc). I think they're a lot of fun, and for under 300 you get a good park ski. From what I've read the fujative is a little stiffer and doesn't have the "butter zones", but you can still throw them around. Alot of people have been saying get whatever is cheaper. Personally I think the deciding factor is if you really want to butter or have a more stable ski. Anyways that just my two cents don't decide just from my opinion.
