We post-expose both sides of any WB/DC base plates (150/48 or 180/48).  We're using Aquasol HV + Diazo.  We can often get thousands of prints out of a screen like this with little-to-no breakdown.

The 225/48 or 225/40 or 300/34 or 300/40 doesn't seem to care either way.  They are pretty bullet proof either way as long as the initial exposure was sufficient.

Looks to me that most people who are using post exposure are firmly in the waterbased ink camp, which is not a big surprise as diazo emulsions are often the hardest to expose...at least the longest to expose. I used to use a peroxide hardener back in the day, worked pretty good but made reclaim a huge headache as we made double strength emulsion remover....still better to have your reclaimer work harder than have a press go down.

Appreciate the feedback, as always for me this is about gaining some insight into what people need and trying to find some solutions to these issues.
Nothing is more difficult than the art of maneuvering for advantageous positions.
