Well part of it is the rider but for example i have a skidoo tundra 250 which has a longer track and extremely light, and i could throw it around so easy its amazing, but no matter what in any powder you have to have full throttle or your going down, my 440 on the other hand does not handle powder very well, ohh and dont try to carve it doesnt work. Just pick your battles when it comes to going through deep snow!! (and take a tow rope with you just incase) have fun!
