the banana magic is very similar to the t-rice and is a cm narrower. it is great for all the things you mentioned.
if you want a good board for riding pow, pick up a pow specific board, i picked up a charlie slasher for 320 bucks at my shop, other good ones would be the jones hovercraft, salomon powder snake, and next years battalion camel toe, all those are right at 400 bucks and i would say its worth it, they make powder much easier and more fun. There will probably be some killer deals on these boards at the end of this season too.
Dude, suckin at somethin' is just the first step to bein' sorta good at somethin'
