AT LEAST 169. I am not as tall as you but there have been several times where I have wondered if I maybe should have gotten the 179's. I'm 5'8' 205lbs., with my weight sometimes the tail is too soft and butters out from under me on backseat landings.
I have about 20 days on mine so far and they have been killin' it. I love them in the park but anywhere else they can be really scary because of the soft flex.
