Actually, SFX is an extended-red film, not an infrared film.  There shouldn't be
much difference between a #25 and #29 filter.  I don't remember the EI at which
I shot the film when I tried it (I wasn't too impressed with it), but thinking
back I believe that if you knock 1/3 to 2/3 stops from the suggested speed you
should get proper negatives.
