In general you gain a little and lose a little with tubliss. Meaning if you run low pressure you gain traction but lose side knobs and trash the sidewalls. The fix for me was to use firm sidewall desert tires and stay away from light weight MX tires. When faster guys run soft mx tires they have to run more air pressure to not lose side knobs so they end up with less gain then the slow guy who can run 5 psi and not ruin the tire. The fastest guys I know run bibs or HD tubes with standard pressures. I'm slow and love the low pressure with tubliss and a hard desert tire combo. I've staub flat many times but every one of those would have been a flat with a tube. The traction to play on an enduro like a trials bike is the best part of having tubliss. Tubliss also protects your rim from rock dents because of the 360 degree rim lock effect. If you go with Tubliss as a traction device you won't be disappointed. If you don't mind the extra weight and want stone reliability go with the bib.
