I'm running Mr Tuffys on 100PSI Kenda Kwests, over 1500 miles here with about 2 puncture flats. Both pieces of trash went through the liner! One was a 2" finishing nail, the other was (not kidding) a toothpick, the fat resturaunt kind. I've had a couple of other flats, mostly from cheap tubes splitting. The tires eventually get chewed up from being punctured and riding over trash, but they're cheap enough, I just buy another set and swap the liners over.
If I had money, I'd run Schwalbe Marathon Plus's. If I had a LOT of money, I'd have Schwalbe make me a batch of them out of blue rubber.
