I meter through an 87c filter when I shoot HIE.  I use a Konica HEXAR which
has an off-lens meter.  I simply placed a piece of gel in front of the
meter, and rate the film anywhere from 3200 - 6400 depending on how much
contrast I want in a scene.  3200 seems to give less, and 6400 give quite a
bit.
