Before Sea Otter time, No-Tubes' Vel-Crow 2.0 tires should be on the market. I would be severely disappointed if these would not be the fastest rolling MTB tires on earth, especially mounted tubeless which they are designed for. I think, providing the tire is ready, many riders will use the Vel-Crow in the back, maybe with the new (and apparently ready) Kenda Karma up front. Of course the rear tire decides 2/3 of rolling resistance, and on climbing courses a bit more probably. Even if you have a Fast Trak or even Exiwolf as a front, the bike will still roll well as long as the rear is top notch.
Only if climbing traction is vital I would pick the Nano as a rear over the Fast Trak. In my experience they roll pretty similarly, but as a front, for my riding, the FT is simply superior. Volume, grip, confidence and predictability. Maybe if you start riding your FT's next weeks, or at least on, you can wear it out a little before SO and there mount it as a rear.
If I can find the funds, and the tires, for my '06 race season I'm betting on a rear Vel-Crow, front Karma. Unless the Vel-Crow surprises me as a front too. Low pressure, super-suptle, it just might work for my lame but twisty trails...
