I am having a hard time picking a track length. I am snow checking a 2013 pro rmk 800. Need some help from all of you out there that have had some experience with both track lengths. I am currently riding a 05 m7 162 and cant wait to get a new sled. I ride as much powder as I can fined in WA but our snow can get wet and setup. My weight is 160 no riding gear and I only ride trails to get off of them. I would put my riding skill level as advanced beginner out riding my current sled need more power. Thanks Nate
