While I'm a big proponent of tubeless, I've never thought that it was an end all, be all. Like most things, it's a trade-off. For me, it's a trade-off that makes a lot of sense. If I were the kind of person that got one flat every 4,000 miles, I wouldn't have switched to tubeless, either. As it is, though, there's not a chance in hell that is go back to tubes on my primary bike.
