	We do a blind trial by using it in one of our Embedding Centres on
                PM blocks, this trials it for cutting compatability
                first!    Then, again on PM blocks, we try processing
                one batch only.

	Yeah, OK, but I would want to know exactly how those blocks got
processed,
from specimen receipt to embedding, & then I'd still want to test it - see
scenario #1.

	I would have grave reservations about trials on anything I did not
control at every stage!!!!!!!
