Geo,
I generally don't replace my stock track until it starts to take a set. Here is an example of the stock track compared to the CE2.5. I was riding with a buddy at Blue Lakes, California. Overnight we got 4' of new snow. That day He was stomping me big time. Went back to the trailer that night and replaced my stock track with the CE2.5, next day I was stomping him. Granted this was Sierra cement but the CE2.5 is my track of choice.
Good comparison.
Also to note the extra day after freshies helps the ce 2.5.
