Hey ya'll, I recently purchased a 173 CM Montero AX, from the recommendations of my Ski Shop and the Stockli website. I am 5 ft 9 and 160 pounds, advanced skier. Do you think I should size down? Would it be noticeable maneuverability? I found the Ski's at Mardens in Maine at 50% Off, and thought I couldn't pass it up I've demo'd the 173's and my wife thought I looked fine, however the ski's felt that it took a bit of effort to turn, it could of been my 90 Flex boots, which I've since upgraded to 130, so I am hoping that with my new boots it should help flex the ski, and make for a fun, maneuverable stable ride.
