We all know UST are the shizzle, just make sure you can get that stinking valve off if you do puncture. Mine was siezed solid after 2 years on not being touched, and was actually rotating the inner lock nut thingy in the rim. Basically spin over. Even pliers back home where no use, I'll have to cut the shagger off.
So Dons tip of the day, check your UST valves are not over tightened.
