Based solely on the number of goatheads I physically pulled out of my tires mid-ride yesterday, during that 75 miles I would have recorded no less than 3 flats. All three bubbled sealant for a moment then stopped. The front had just one removed (which doesn't count any thorns that broke off in the tire) but only lost 2psi overnight. The rear had 2 monster thorns removed, and lost about 8psi in 24 hours.
Out here, tubeless is only a choice if the other option is "fix a flat every single ride."
