Just heard John Skinner from University of Tennessee give a talk about
their research into this.  They found that the black plastic frames and
black foundation did almost well as wired beeswax.  Plastic frames didn't
hold up in the extractor as well as wood.  Other forms of plastic
foundation did quite a bit worse as far as getting worked by the
ladies  Without having all his numbers to share, I came away thinking to
keep wiring beeswax foundation into wooden frames was by far the best for
my situation, yours may be different.
