i have ridden both the fujatives and invaders and they're both solid skis but personally i liked the fujatives betterd cause i ski about 70% all mountain so i like a stiffer ski. The invader is fun though and really light compared to the fujitives as well.
just go with the fujy's. i've heard a lot of people talking about breakin their invaders. my old pair of fujy's i used for like 4-5 urbans and they are still holdin up, it's ridiculous
