I know a lot of people run tubliss and really like them. I have them and I'm on the fence. I typically ride very slow rocky technical single track fairly close to home and have run the Bridgestone UHD tubes for years without much trouble...sure I have gotten a flat now and then but I'm trail riding, not racing so changing a tube on the trail isn't terrible, but you have to carry one, especially when running a rear trials tire. Over the weekend, I did the Hancock NY dual sport which has much higher speeds and sharp shale rock everywhere. I had tubliss in the rear with a dunlop d803 tire @ 12lbs. up front I just had a battlecross x30 with heavy duty tube. At the gas stop, some guy in line points to my rear tire and asks "Do you intentionally run your pressure that low?" I don't even look back and said, yes. then I look back and see the tire is flat. But the weird part is it was probably flat for some time and I never even noticed it, not even when I was pushing our bike at the long line to the pump! Luckily the station had a compressor and I was able to find a tiny hole in the sidewall and plug it using standard car plugs. I was able to finish the day with the plug, but it looked like it bot pushed/pulled out a bit by the time I got back to the truck.
