If you trust your handling procedures, just straight pitch it. Think about it, you could just straight pitch several vials of yeast, you don't have to 'wake' it up. Once it is in the wort, it will know what to do.
If you have any issues with your yeast or handling, then make a standard 2L starter.
I don't trust Mr. Malty viability figures, I believe yeast slurry stays much more viable that it predicts.
