Well after trying to find a used sled on kijji i have just decided to go brand new. So here is my problem should i get a Assault or Rmk ? I ride a lot of flat land with ditch banging etc........... and I ride the mountains 4 to 7 times a year. I have heard that the Assault track just digs into the powder and is very hard on sliders. Does any one still have with the comp track on it? Looking for any help. Is there cooling issues?
