How would it affect performance if I bought a 156 or 158 wide board? My feet are size 9.5-10 but I've noticed that wide boards are recommended for feet sz'd 11.5 and up.
I totally thought 156cm would've been too small. I'm going up in a CAT in March but they're going to have Burton powder boards to ride for free so I was thinking of all all mountain / freeride board that was at least 160cm. From all your comments, sounds like 156cm would work just fine.
