hi mark

condenser enlargers need less developing ( 30% less ) than cold light head
electronic duplicating devices might be inbetween the 2 ...

you might consider a film test .. 2 rolls
bracketing your exposures ( one at box speed, one at 200 ) and
processing your film 1 at normal ( for 400 ) the other for 200

and see which one you like the best.

what i like may be totally different than what works for you ..

have fun!
