regulated (300-400psi) = 2K+ cockers w/ internals that are low pressure high volume friendly. (grossly over-generalized)... and a decent reg designed for the task.
e.g., start with an operating pressure and build to that pressure. cocker internals were made to work at a fairly specific* operating pressure. Pick a pressure and work backwards. *(again over-generalized)
Sounds like 2 functional body types and 2 functional valve types then.
Probably too much to ask for criteria to be applied evenly.
