If you have the money and time, you should pick a couple and try them. I've had Acura, Honda and Nissan MT's and they all liked different MTF's. I only used Redline or Amsoil. In one, the Redline shifted smoother and in another the Amsoil shifted smoother. The Redline seemed to last longer before I noticed a difference is shift quality. Molakule was my source of info.
From what I have read, I would definitely give that Ford XT M5... a shot.
