Is my old board wrong for me?

I bought a board about 10 years ago and only used it once or twice a year. I've never been able to build much skill do to lack of practice. I would like to make more of an effort to build up some skill next season. Back to the question at hand, I'm 5'11" 185 and the board I have is a K2 Spitfire 150. Would I be better off with a longer board? What adverse affects would I encounter with a undersized board?

Yes that is a quite small board for you, it would basically be a park board to throw around tricks on the ground and off jumps for someone your size. I'd guess you'd want a 156ish ...

Mainly more stability. A longer board will be stiffer and able to handle you going faster with less worry of eating it.

more stability at speed, better float in powder

that sounds like what i need, once this board gets up to any speed it seems very unstable
