By the time arctic cat gets a real engine and drivetrain, canam will have dropped the fancy 3wd golf cart design with high COG and gone with an off road racing inspired chassis. Then there will be no point in a popo or cat.
No comparison to the rzr 4, and I had the dragon fire full suspension on the rzr. It is a little bigger running though the trails but the throttle response makes up for it on the real tight areas. Seats are so much better, ride is great...no squeaking (I finally quit greasing the rzr and the squeaks stopped)
