153, The 162 was a little to hard to control for a guy my size, 5'9 165 lbs. The 153 seems to me to have the best of both worlds, can climb and powder with the 162 and eaiser to boondock, I ride a 07 M8 and can stay with MBeeson's 900 162 (sorry mike, couldn't resist)on the hills and in deep powder.
