I have no direct experience, but the "ghetto tubeless" option is there as well. It involves slicing up a tube and using that as the rim liner, then using Stan's sealant inside the tire itself. You get to use pretty much whatever tire and rim you want, and can switch back to a tube if the worst happens while out on your ride. Offroad guys like it.

Back on-topic, hope the RibMos do the trick!
