Last year I bought a 2008 Summit X 800 with 154", and in bottomless powder it is unbeatable, but in under 2 feet it is just soooooooooo hard to lean. My 2002 800 w/151 is easier to make uphill turns with. My wife's 2004 REV requires so little effort to tip, given the '08 is 'smoother,' but it just takes too much effort. I love the light weight of the XP, but I don't like how it rides and corners except on trail and in 4+ ft of pow. I'm going to look at some 2007 X-RS's next week, I figure with the extra money from selling my '08 I can mod out an '07 X-RS a bit and make a monster. What do you guys think? To give you an idea of my riding style, I live in Northern Utah so I have a diversity from shallow, hard snow to 6 ft of powder. I don't hillclimb that much, mostly boondocking, jumping, and messing around in powder.
