hey! i was looking to upgrade my 1998 polaris xlt special to something that is a better ditch banger. i have narrowed my choices down to either a 2005-2006 polaris iqr 600 or a 2003 or newer skidoo mxz 600 or 2003 or newer skidoo mxz 600x. if anyone has any experience with these sleds that would be great! thanks!
