I am 5'11 and used the 164 cm. I like a shorter ski for my height because I am new and I like to go slower and not feel like I'm out of control. For your height, the 164 would be best, unless you like to ski on something really long for you.
After demo'ing them this winter, I just purchased these. They initiate turns incredibly well, which is what I needed. They're flexible and easy to control. They ski well in all conditions.
