Everything omes down to your personal preference and style of riding, but I am 6'2" 175 lbs and I wear a size 11 boot. I ride a 153 Stepchild Jibstick with 6mm of rocker and I found myself riding it in some semi-deep pow one day when it was dumping.
It did great... better than my 157 reg. camber board. I bought the Jibstick just for jibbing (80% of my time), but once I got it I didn't ride any of my other boards even on cruising days because it was just so much fun...
