Mamiya TLR lenses aren't very Sharp--they were designed for portaits. I had 6 of them in almost every focal length. The chrome lenses are sharper (I have the finest, sharpest 35mm enlargers & lenses, so maybe the comparison to Mamiya TLR negs wasn't quite fair to Mamiya).
Chip, I am thinking perhaps you have an inferior enlarger lens, or some other problem developing medium format. I find my black 65, 80 and 135 Mamiya TLR lenses superbly sharp, especially the 80mm. I feel it is sharper than the 75mm Xenar on my Rolleicord IV. The only drawback with my C330 is the size and weight. It is a bulky heavy outfit to carry around your neck for travel or whatever.
