I would go with Rollei Superpan and use an rm72 filter or a #87 if the subject permits long exposures. I have also had excellent success with Rollei IR.

I have had decent success with the Efke IR films but I have also had spurious quality control issues. The Efke IR probably has the deepest IR sensitivity on the market right now, and if you like halation they have the version without the AH layer.

One slight mark against the Efke for colour sep work (which will require several good negatives) is that it scratches more easily than the Rollei. Of course, you could simply be more careful with it...

For me though, superpan is tops.
