if you have the means, deffinately get 1. that M-10 is sooo smooth. the only problem with it is it doesnt transfer weight as good as the edge susp., but we're gonna mess around with it and see if we can help that. as for the back end feeling loose, that's just the M-10, studs will deffinately help that. i have a '02 edge x with M-10 and love it. i dont know about fuel consumption as mine is an 800 and goes thru ALOT of gas. i think the 1" track hooks up pretty good, although, my lugs are ripping off. i'm guessing the new track's are better as i havent heard anyone else complaining about them. all around i'd say they are a great sled. you might be better off waiting till next year tho, my club pres. works for a dealership and said that the '04s arent gonna be worth much next year with the new style coming out, not sure if thats true tho. good luck
