Iím 5'7, 165 and went with the 156. I feel itís the perfect size for me. I have the Rice in both 153 and 157. 153 is good for playing, 157 is big on me. The HK in 156 fits perfect. Its narrower then the Rice boards too. If you put a 157Rice next to it you can clearly see the difference. If you can demo it do it, or just buy it lol.
So you can really feel the difference in the hotknife with the nose leading the board instead of from the middle/back of the board.. thats what im looking for..something closer to my traditional camber board but with a bit more playfulness.. the t.rice feels squirly when riding flat or going slower..when i bomb down the mountain, it feels great though
