Don't forget about Rollei Retro 80s. It is a couple of stops slower than the IR400 but it is exceptionally fine grained. Someone published some film test data on APUG recently that put it up there with T-Max 100 and finer grained than Pan F. It builds contrast quickly so requires careful development but I really like the tack sharp look and I think high contrast works well with IR photography. It's a very different film to HEI.
