148 or 154 size snowboard?

I'm looking at a 148 and a 154 on ebay. I've been out of the snowboarding scene for almost 4 years now and have forgotten alot about snowboard specs. I used to ride a 147, but I have Medium bindings and size 10 boots I'm using and the guy selling the 148 said if I have size 9 boots or bigger that I should go with a board bigger than a 148. Can some of you Shaun Whites out there elaborate on this for me please? thanks.

148 or 154 size snowboard?
Board size is more dependent on your physical attributes, as well as what you like to do on the mountain.





If you're short, and light I'd say, 5'6", 150 lbs or so, the 148 might be good if you like to jib (hit rails and ride through the park).





If you're anything over that, regardless of what you like to do, I'd go with the 154.





Summary:





Bigger body = Bigger board.


Big boots = wider board.


Park/freestyle rider = shorter board.


Groomer/powder rider = longer board.
Reply:Get em both!! one park killer and the other as a all mountain rider. werd.
Reply:that is a really poor worded question.





Anyways,


I know nothing about your body and thats what counts more.





Size 10 is barely above average foot size and you should be fine.
