Dear LH,
That's news to me (but I think that it's wrong or you must have misinterpreted the information).

In the past, FIRST has allowed us to use a Norgren primary regulator set at 60 psi and a secondary Monnier regulator that can be set to a lower pressure. I haven't read anything indicating a change from that policy.
In our case we used and set the Monnier regulator pressure lower because the force to raise and lower our aluminum hopper is very small and we can save some air (pressure) for the cylinders used to raise/climb our robot during the end game.
