Depends on what you want, really. The TM is a little wider at the waist and (I think) it has more sidecut than the MT. If you want something a little quicker edge-to-edge, the MT may be better for you. If you prefer a little more underfoot, the TM would be better. If you like a straighter ski, get the MT - if you like a ski with a bit more sidecut, get the TM.
