My next bike I'm going UST (probably stuck with disc brakes which is why I dont get it now). Goatheads out here are bad, and in one week I had 8 flats and was spending over $100 a month on tubes. Since then I commute to work on my tubeless CX bike, and most of my road bike or TT rides are on Gatorskins. If UST works half as well as my CX tubeless and as well as the UST system is reviewed it will be a great buy. If not, I can just put my GP2k's on them.
