Mark, I've used Hasselblad lenses on the Contax 645. It doesn't matter if they are CF, or CFi, or CFe. The 100mm and 180mm (and 250mm SA and 40mm IF) are particularly fine performers, so they're the obvious choices.
However, my own experiences weren't particularly encouraging, I used a 180mm and even though it delivered slightly better results than the Contax 140mm and 210mm it still wasn't quite as good as when it was mounted on a Hasselblad body. My take out was that the adaptor (which was the Contax branded adaptor) wasn't perfectly aligned.
