Picked my my 155 boost late winter last year and had planned on doing a 165 2.75” track for the mid winter dep snow track. So got a track and 165 ice age rails. With the poor snow conditions never replaced the 155. Now that a new season approaches I really like the look of the Lynx 3” so got one of those to try. Should be a really hood deep snow track on the boost. Weighs a little more than the 165 series 8 2.75” track. I think what little I may lose in track speed with the 3” lug, I will be see bigger gain in traction and forward movement and ground speed.
