After learning to love the 174 xm the last two years I was anticipating buying a 17x length with all the new changes. Ski-Doo has done a great job on advancing the mountain segment and we are all going to be better off because of the great competition between manufacturers. However, I am not sure I will be able to justify a new sled that will have a smaller footprint on the snow.... Makes me think about waiting another year (X174 is same as '16)... Any thoughts?
