Snowboard Help Please?!?!?

Okay so I was planning on buying the 09 forum recon 158 wide and no one had it other than ebay and it was listed wrong.. I can find a 156 wide for cheap and i really need a board and under 250$ should I just go with the 156? Would it be fine?... Im 6'2 185lbs. and i know traditionally people are just like woah go in the 160's people are like go between 155 and 160 and i should be fine.... any help or suggestions on what I should do??? what would be the difference if any
