Does anyone have a 2002 Polaris 700 Classic, or a Polaris 700 XCSP with the M10 suspension. *I would like to know your thoughts on the performance of the M10 compared to the Edge suspension. *Does it give a good trail ride? *Is it easy to adjust? *Does it affect the gas mileage? (my son has 700 XCSP with Edge Suspension and gets about 17 miles per gallon) *Thanks for your help.
