My current board is too wide, my bare feet are a couple cm on each end from reaching the edge of the deck (even further from the edge of the base).
It's really not that big of a deal. I feel it as I carve, but mostly only at higher speeds on wider turns, it can be really difficult to pressure each edge hard enough, which I think a narrower board would help with. But if I'm getting a new board, I want to do it right.
I have small feet, size 7.5. 23-24cm in length. Because board width is typically measured at the waist on not inserts,I'm guessing I want a waist width in the 22-23cm range, so the length at the inserts (at my stance angle) will be about the same as my bare foot.
I weigh 150lbs. My current board is 156cm, which is perfect length for me for carving (its short for powder). I want my new one to be a bit longer for higher performance in powder, 158-159. And I'm looking for either a rocker-flat-rocker or rocker-camber-rocker, on the stiff side of the scale.
Any suggestions? Should I be looking in the women's section? Bonus points if it's available as a split.
Also, this is where I got my info about width http://www.wiredsport.com/blog/snowboard-width-huh
