I have a 162" x 16" CE on my RX-1 and a 153" PC on my M8. The RX-1 NEEDED a big wide track to make it float but, boy oh boy does it float great now and with the CE it rockets out of a powder actually lifting the front end of that portly sled into the air in the deep stuff.
In similar fashion, the PC on my M8 seems to dig into the powder (but it seems to sink more than my CE) and often times when I think the sled is going to sink out of sight, the PC hooks up on a layer of snow several feet down and saves the sled from sinking.
The CE is like the M1000. It's a little bit on the heavy side and it's not fancy or frilly but, it flat out works.
The PC is more like a M8. It a little lighter and seems to use more finesse (vs. brute force) to coherse the snow into doing what it wants it to do.
Bottom line is: they both work well yet use completely different techniques to achieve success.
I do have a couple of questions.
Is there enough adjustment on the rear axle to be able to run a 156" track without rail extensions?
Also, it looks like it fits well without any tunnel extension, Right?
How about up front around the front axle? Is there enough clearance to run the CE without any trimming required?
What's the weight difference between a 153" PC and a 156" CE?
