I'm kinda suspicious of road tubeless because of the need for the carbon fiber beads and special sharp corners to prevent blowoffs. Also, I like fat tires and there just aren't 30mm supple tubeless road tires yet.

Tubeless Hetres sounds pretty hot, though... the pressure is as almost as low as MTB tires, where tubeless is already well-proven without needing any kind of special beads to prevent blowoffs.
