Replying to Front Flips

Easily my favorite trick on tramp right now (superman of course) and want to take this to snow. I took backie this summer to snow and I think Front flips should be my next flip to try as a I can't cork or flat or rodeo lol. Im wondering the difference between knuckle style front flips where you push off of each ski one at a time or doing the more "functional way" where you just extend your body out and flip. What one would be the best to try for my first front flip off a jump? Is there really a difference?
