Unfortunately ROLLEI IR seesm to only go as far as 820nm. KODAK HIE went well over 900nm...

Yes, the Rollei (and similar) film only pokes a bit past the visible red. To get "true" IR effects I find that deep filters and rather large exposure compensations are needed with this film.

Let me suggest superpan and a deep red gel over the flash.
