If the "Good" performance route will be chosen, a route that will require both the Janus and the OZY cards, which will 
be the plus side of that choice ? We know already what the minus side is, a reduced performance compared to the Horton 
card, but what about the advantages ? IMHO, the only advantage will be a small reduction in cost/price. Can this 
reduction be put down in numbers ? I don't think it will be significant, so the "Good" way, as opposed to the 
"Excellent" one, doesn't look as being much justifiable.  Just my two cents.
