Unowned

Hey folks

I've been riding for almost two years now and I've recently started taking an interest to jumping. The only two snowboards I have ever ridden are the burton ltd/cruzer (resort rental junk) and my own Burton Deuce. I find that its difficult getting any air with the deuce, i dont know if its really due to the stiffness of the board or its because i just plain suck. I've watched many tutorial videos on basic ollieing, but i either dont have the mechanics down or ..well i don't know.

I'm even contemplating buying a new board...been eyeing the NS SL 153 (wish the 151 was in stock and on sale). Is 153 too long? I ideally would like more manueverability, but im afraid my lack of weight may disagree with this board length.

Anyhoo, any additional tips or pointers would be great...

My info
Burton Deuce 152 / Burton Triad Bindings, 5'6" 140lbs, sz 7.5 boot
All mountain, interested in terrain park but i need to grow a set first...
