Because this is BF and almost none of us can resist suggesting he equipment, consider the WTB Resolute tire also.
I am using these tubeless, and they fly compared to the 120 TPI MSO, and I actually really liked the MSO.
The Resolute measures 43 mm wide on a pretty typical witdh rim, so that may be an issue, but if it isn't then definitely consider them. Bikeinn.com sells them for $35/which is probably 20 less than the MSO.
The tread blocks are more pronounced on the WTB, but review after review backs what I sense which is that tread does not make that tire slow.

Really though, there is no wrong choice with what you are considering. They are all quality tires over all.
