Medium Format Infrared

Hi,
I was curious if someone could recommend a good 120 IR film?

I've primarily shot 35MM IR using Kodak HIE. I like the qualities of the film, particularly the resulting effects caused by the absence of the antihalation layer. I've had a heck of a time getting a decent enlargment beyond 5x7 from it, unfortunately.

Thus, I'd like to do something similar with my MF cameras. Any info would be appreciated ---
