Great reviews, keep it up. The information is invaluable. I'm coming of a 10/11 NS Evo 151 (I just unloaded my entire quiver onto craigslist after finding this deck). However, I was eyeing a NS SL 153 but I couldn't live with the directional flex ... I want a true twin.
@Oskar I think I mentioned it above but I go about 210 lbs and I rode the 57 without any trouble. If I were buying one I would probably go with the 160, but I've also got 30 pounds on you. You should be OK on the 157.
I range from 195 to 205 pounds and the 157 works great. I really like the board. Not saying I wouldn't ride the 160, but I have many other boards in that size. Right now in my quiver I ride a 157, 159, 161, 164, 168. That is why I got the 157 Proto, wanted to go a bit smaller and I have not been disappointed.
