Both are great tracks but I think you would be very happy with the 121 cobra. The Cobra is better in loose snow if that's the main factor. If you have had a ripsaw before I would try the cobra or vice versa that way you will know what you want and like. I like to try something different that way I know. I have a fusion as well and I 'm going to try the Ice Ripper XT when it is time to replace. I would just pull the trigger and give it a shot.
