I am running Mohawks with the X3. They are an improvement. However, they are grabby in crust and heavy snow. I had mine slightly modified (similar to the mod for the Powder Pros). It made a vast difference in the responsiveness of the skis without sacrificing any performance in deep snow. Highly recommended, especially if you are running the X3. They work quite a bit better than the stock Grippers even though the Polaris skis are very good for stock skis. Lots of Arctic Cat guys out there that will buy the Grippers to replace the stock POS skis that come on the Cats. I sold my Grippers in less than 24 hours after listing them. I had over 10 inquiries within a couple of days of listing them.
