The sled I rode all week was a 155 9R that had the 3.25 track on it. His Ultra Lite had a different 165 track on it. To my knowledge at the time he did not have a 165 with the 3.25 track there. The only sled he told me not to take pictures of the track, was the sled I was riding. It's kinda funny because I just looked and there aren't any pictures on his IG of the Ultra Lite track. I only rode 2 sleds when I was in CO. The 155 9R and his Ultra Lite. The Ultra Lite is obviously a 165 but the difference in the way that got on the snow compared to the 155 3.25 was astounding. I have a picture of his Ultra Lite track but I don't want to piss him off and post it. I can tell you, it's nothing like the 3.25 Series 9.
