What are your thoughts on the adjustable combination valves? Dave Lenzi told me about them and thought they had some very good promise as far as limiting the pressure applied to the rear most wheels.
There are a lot of new items out there and I want to keep an open mind. I am sure there were very old time cable brake guys who thought hydraulic brakes were too complicated, unnecessary and too much could go wrong, but here we are.
Take care,

Tom,
There are two different issues here.
Reducing the pressure to the way rear to stop them from flat spotting the tires is, in opinion as a refugee from brake testing, a sub optimal answer.
Getting the way rear to stay on the ground so you can use those brakes is a much better answer.
The wrong combination valves did reduce the possible brake action, and that was no advantage. The was a notable difference in panic stop with the rear pressure reduction removed.
Then, there was my father, as he quoted the Ford advertisements that said,"The safety of steel from pedal to wheel." He and my brother worked for several days trying to get the brakes balanced on the Model A that he was restoring. He did confide that in the early days of hydraulic brakes, there were some reliability issues. And remember, they were all single circuit until the mid 60's. If you are old enough to have driven a single circuit brake car and had a failure, you know what a bad feeling that is.....
