I'm planning on getting into snowboarding this year and I might buy my stuff online. I started snowboarding last year and went prob 4 times on rental boards, so I can pretty much keep myself up on intermediate hills. I did the sizing guide and it says my board size is 158 and board waste width is 152-153 (not sure if I'm better a 10.5 or 11 boot size).
My main question is if the only two options for boards are 157 and 159, should I go shorter or longer board? I plan on doing all mountain and mainly keep to the hills. Also for bindings, since my feet is around 10.5 - 11, would I go with medium or large bindings?
Also, if anyone has tried or own these boards I'd really appreciate the input as I'm really considering them

. 1) Nitro Magnum gunslinger 2) Nitro Team and the Rossignol Premier (If it matters, they're all the 2009 model). If anyone has other boards that might be good for my size and skill level I'd love to check them out. Also any advice on which bindings to get? My budget for bindings is $150 - $170.
