My first test print

[motcon]

. Neither affect highlights (except that the filter blocks some light so exposure may need to be adjusted compared to printing with no filter).

try printing with an 00 filter two stops over normal print time. of course it affects highlights...

try printing with an 00 filter two stops over normal print time

If I give the print 4 times normal exposure (2 stops) it is definately going to effect highlights, whether I'm using contrast filter #00, or #5, or no filter at all. Exposure is used to control highlights.

Anyway, I'm not going to say that there is only one way to print; whatever floats your boat and gets you safely to the other side. Where you got my interest was with the statement "shadow detail is unaffected by any filter under 3 1/2....." I'd never heard anything like this before, and it seemed to go against what I experience in the darkroom. Several days later, after looking through books and searching the internet, I'm still unable to find any information regarding this.
