Yeah, I run 3 mil tubes, they do work good. The norm around here is 13 psi. I usually run 17-19, so it's been awhile since I've gotten a flat. The problem is that at that psi the tires aren't as consistent with gripping. I was just feeling out opinions to see if it would be worth the bucks to get my tire irons, pump and patch kit out of my Camel pack. A year free of those things and the comfort of riding with no fear of the jagged terrain and pinch flats. ;)
