I've been road tubeless for four years. At the beginning there was Hutch tires only. Then Schwalbe Ultremo -> One -> Pro One. I've had Bonty R3s (yikes!), Spech Roubaix Pro & S-works Turbo and currently IRC RBCCs. Sealants I've tried: Stans, Orange and currently Stans Race. Looking forward to the non-latex stuff soon.
I run 25mm tires but my '13 EVO chainstays and wide HED Belgium+ rim only allow a 23c on the rear(which measures 25 on the rim). Pressures @ 72f / 100r (I'm #175). Punctures that did not seal? A few - and all in the back. that extra pressure really does make it hard. I've held my thumb over geyser holes a few times (in 20,000 miles). Sometimes they've held. Sometimes not. Either way they've dropped to 50psi and if you try to inflate back to 100psi they'll let go. (Read: not had a front puncture for 20,000mi except riding into a square rock.)
Sticking with tubeless? Yup.This setup has gotten me over much gravel, bad roads and even some of the Grasshoppers when I did not have a 'cross bike. The tires feel great too.
A quick word on Schwalbe Pro Ones. I've had two 25c up front - good tire - good grip - 2500mi life. Rear (23c) got only 200 and 700 miles before abandoning them from many small punctures or tears. They are lightweight and have weaker sidewalls for some places I ride (at 100psi). I preferred the old "One" tire.
