I'm 6'0, 165. After agonizing, I went with the 184. Skied them for the first time today in 6" of cut-up fresh at Beaver Creek. I had a total blast. The 190 might give a little more high speed stability, but for pivoting through trees and bumps (trying to find the stashes after the powder is gone), I thought the 184s were phenomenal. At no point did I feel like I needed more ski. Totally agree with the stable-yet-playful comments, btw.
