The master I use is the modern style aluminum piece straight off the truck in the junkyard years ago.

I do have a twiddly knob style valve in the rear lines but it didn't need any twiddling when I upgraded to the larger brakes.
I can roll on the brakes and increase pressure until they lock. The rears lock just after the fronts. It takes a little pressure to get to that point but you don't have to stomp on them.
It's a really nice setup.
