IMO, go with the Everest. Unless you want to know what elevation you are riding. ALL SKI DOO SHOCKS SUCK, EVEN THE Xs. My Everest runs just as good as an X. All the X guys I know have ditched their tracks and gotten the one that is on the Everest. They hated them. I don't know about you, but my decals come off right away. Ski Doo isn't changing anything with these at all. I'd grab the Everest for 8800. Thats a deal, I had to pay 9200.
Chit, I just checked my dealer's website! He is selling an Everest 154 for $8650! I should call and complain, he told me that 9200 was as low as he could go!
Regardless of what people think, the "X" sticker DOES NOT add horsepower. Use the money you save and snag some Fox Floats, less weight, better shock! Flowrites in the airbox, and install some sort of vent kit in the side panels to release the hot under hood air and to keep the clutches cooler.
