You'd want to stick with the 2 1/4 condenser. The 4x5 condenser will work too
I think, but not be as bright.

Thanks. The 60 mm WA lens I'm considering are made for 6 X 6, so that's not a
worry. I WAS wondering if I should use the 50 mm supplimentary condenser and
if THAT would cover medium forma? If not and I just use the basic condenser,
will that give even illumination? I think B8s, like non-variable condenser B2s,
require a closed match between lenses and condensers that most other condensed
enlargers.
