Sounds like the Stop Flats2 is really working for you. I use the similar Mr. Tuffy on my pavement bike with only an occasional flat. Been using Rhinodillo liners on my emtb and I still get plenty of flats, like ever 3rd ride or so. Going tubeless with the Stan's stuff tomorrow on that bike. I never had any success with Slime and it makes such a mess and nearly impossible to patch a tube.
