It's a really impressive sled, especially for the price. Starting with a used 2013 Pro, you could get it done for less than the cost of a new sled. I'm running a 3" on my m-series right now with a stock motor and that track completely changed the sled. First mod I will do from now on. I had to put a kmod on it to keep the skis down, but it sounds like the Pro is better balanced and won't have that issue.
