I was in the same situation as you. I had a 2008 burton blunt wide 158. I'm also 150ish and 6 ft tall with size 11 feet. I picked up a never summer sl 2012 151 for 349$. I talked to a never summer rep and at its waist of 24.3 they said it will be just fine with my boot size. The type of riding you do is identical to mine, I've heard the sl does it all.
