I ran my SS with my old Rampages (29 X 2.3) today and what a difference. I have been running it with Maxxis Aspens (2.1's). The Aspens are very light (sub 500 grams) and roll great. They are in my opinion the perfect XC tire where you still need good traction. That being said, they are not a great "trail" tire. Running Boyette today, I was really amazed at how much "cush" you get from a higher volume tire. Traction was limitless and the extra weight was definitely offset by the benefits. So again I say, "Roll out your big meat"!
