If you do alot of prolonged 70-80+ mph cruising on U.P. trails then your not going to want to do the 1.75 sno-x track. The sno-x track is not intended for High speed hard pack trails and it will not hold up. (I can't speak for 1.75 backcountry track becuase it is a softer compound and it is not a sno-x track) The upside of the sno-x track is The traction is the best thing you'll ever feel on a loose groomed trail. The track will throw golf ball to tennis ball sized chunks in its wake. Nobody will ever ride on your snow-flap unless they're a masochist. The side bite of the sno-x track is something you have to experience to believe. Depending on how you like to ride that is good or bad. It was really easy to manipulate the front end with weight transfer, which is really useful in whooped out sections of trail. I ran one 3,600 miles over the last 2 seasons on a Nytro RTX. I ran all 3,600 miles on 1 set of slides too. But I cooked the track on my last ride of the season this year. All of my low track clips came off and I broke a few of the bigger lugs off at the belt line. I'm getting long winded here so let me summerize. I love the track, its amazing! but if your going to run them you just better be prepared to replace it becuase its probably not going to hold up like a ripsaw for the trail..... It was a cool experience and I'll have some times next season where I'm sure I'm going to miss it but I'm probably going with the Ripsaw 2 track next season.
