Hi Has any one out there got a new Max 2 from the new owners mudd ox and tried them against the older ones like a 2009 year made one.How much better are they.How much more zipper are they with those bigger engines in them ,a 29 hp in a max has got to get up and go a lot more than my 18 hp one.I want to get a new one set up for the tracks with more power too,but just want to know if it is worth the price?
