Hey guys, greetings from Canada. First of all, used this website for researching the 550F Skandic I bought in 2006. Awesome sled used for work and hunting never let me down, even on 5 miles of of mud and ice this spring. However, with a new member to the family who will be 2 this fall, I was looking at the new Skandic with less smoke, originally the 4 stroke, but lack of a pull cord makes me leary. So what do you guys think of a 20" track with the 120 hp 600 ETEC. Heard lots of good things about this motor, but it is not a cheap option. Any thoughts on motor longevity, I will be keeping my 550 F for the work applications. By the way, I got drawn for a Bison hunt this January in Northern BC, maybe that is the real reason I am looking at new sleds. Cheers.
