Well i am thinking about purchasing a new sled this year or next year. i am 5 10 and weigh 180. i have been thinking about switching over to the cats. but what are the advantages and disadvantages between the xp or rev and the m?? what are the best years? i was thinking bout buying brand new or a one year old or something with low miles any advise there?? i am pretty set on a 151 or 153. is a 162 that much harder to steer? and i am also wondering to sell my old 2000 summit or just keep it. any help please
