I bought my wife a 2010 Polaris IQ-LX 600 with all the bells and whistles. I am sure I put more miles on it last year than she did. I already have a 2006 Polaris Switchback 600 that I just traded/gave to my son for his 2002 Pro-X 440 Fan. He's 6'7" about 220 lbs and I always hated watching him doubled over on that sled and trying to keep up. I myself am 6'5" with many more pounds and know I can't ride it, so I have to move it to get myself something new.
My wife looks at me and thinks I am generous. Not exactly the truth, I saw the new 2011 Switchback Assault 800 and am trying to find one for a "good" price. Talked to my regular dealer but he doesn't have any coming in.
Not what I wanted to hear, but i'll keep looking!
