I'm 5'9", 158#, and ride a 164cm Premier. I have the rear binding set all the way back.
More importantly, if you're not experienced riding deep powder, make sure to look far ahead and make your line choices well in advanced so you don't stop in a low spot or flat spot. Keep your momentum. Read the thread on digging out of deep pow. Know tree well safety. Have a great time!
