Replying to Fujative Question

i am about 5'10 1/2 or 5'11 and i am seriously thinking of getting the 169 Fujatives because I have used shorter skis pretty much the entire time i have been skiing, but i have been hearing some things about getting longer skis, i dont realy go that huge off jumps and i am just starting to learn rails, will getting 179s force me to pretty much re learn how to ski on a larger ski for most of the season when i could be learning new tricks and new rails? And i am not stick thin, so will getting that small of a ski mess up my ski?I am riding right now 160 salomon 1080 vinnies so that will be a HUGE change. give me insight
