I've had only ONE experience with tubeless... it was on an event ride... rode past a woman sitting on the sidewalk in tears... stopped to see if I could help her (ALL the men just blew by without acknowledging there was a problem! what's up with that???)... she was on tubeless tires and had flatted... had an extra tire but was outta glue... and had used ALL her co2 and was flat again... she was a racer and chastising herself for going out without glue and a pump... I told her to ride with us (we were WAY slower than her.... but I had a pump! ) and stopped about every 7 miles to fill her up til she made it back in... I have no idea if her wheelset was messed up or not...

somehow to me, tubes seem much easier to deal with... ???
