I'm assuming you want small cause you have a small hill to be on?
At 165 you should be aiming for like a 152-154...
Look at the Signal Park Flat, Arbor Westmark, or Bataleon Whatever. 3/4 of my favorite fun time boards for 2012 that I've ridden*. The fourth is the Arbor Blacklist, but its a midwide and smallest is comes is 154.
*Haven't ridden a Park Flat, but I have ridden enough Signals and enough zero cams to know I'll love it.
That thing I do to escape the world and have fun with my friends
