I am on the verge of purchasing the Palmer Andy Finch twin snowboard on sale but im torn between a 158 and a 154. Unfortunately the board isnt manufactured in a size between that, but I cant pass up this deal as I'm getting it for around 100. I am 5'10 and 185 lbs. This is a very smooth and flexy board and I will be using this board more for park than anything else but my concern is that I might be too heavy for a 154? would the 158 be better suited for me for overall balance and control on jibs? Thanks.
