I like tubs, and I don't have an argument to challenge any claims for clinchers. All three of my current road bikes are on tubs, and they started out with them right after being built up with the wheel-sets I had on hand. I've not had any regrets or reasons to think about going to clinchers on these machines. I like the satisfaction of gluing and setting up a new tub. I carry a spare in a bum bag, along with my ID, phone and stuff.
