Hello Everybody. I am a snowmobiler making the switch to a Timbersled this year. I plan on getting a Husqvarna FX450 but I am torn between the ARO S and Riot S. I am about 5 foot 7 and 160 pounds. I will be riding in Cascade Mountains in Washington State around Cle Elum / Salmon La Sac / Stampede Pass areas. Please share your thoughts if you have any.
