My bro-in-law had a 2002 MXZ-X 700 with a 136", i had some seat time on it and would take my pro-x over it anyday. The pro-x feels so much lighter and easier to throw around. And they have about the same power.. I would stick with a pro-x over a mxz-x, but the rev is definitely a good step up from the edge/pro-x chassis
