both fun and capable....you don't say where you live and the type of snow you mostly ride in, and therein lies perhaps the most important criteria.....lighter, dryer, higher altitude snow lends itself to a longer track....difficult riding situations in shaded big forests, with steeper ravines, and more exploring where you're going slower as you try to pick lines through unfamiliar territory also lend its' self to a longer track....i ride a 165, my main riding buddy a 154, we both get along fine and both are better traction sleds than anything else we ride with..:face-icon-small-hap
