Once you go Tubliss you'll never go back my friend! I'm on my 3rd season of my first Tubliss install for my trail bike (not a DS). I keep a road bicycle hand pump in my pack which goes up to 160 psi, though I've never had to use it. As long as you don't ride through a bin of nails I'd be surprised if you ever have trouble with the high pressure inner tube. Combine that with the ability to drop the pressure down low enough to grab onto everything like a clamp in the backcountry...well, let's just say I enjoy pretending it's skill and not technology get gets me to the end of the gnarly tracks first
