Fx will need to see if that involve to share part of the "pie" or that will make the "pie" bigger, anyway is a great problem to have! jaja
The impact can too produce more at higher reg pressures, but remember that until AMP reg the max pressure on the Reg was 150bar (after that no warranty) unless you change to a huma reg. Now I am just thinking outloud ... since I do not have experience on the RW electronics, but I think it control also how much time the solenoid is either open and close, with the impact, only closing to fully open the valve and keep it open for x time .. no.
Anyway, I think is a great idea to mix those (stx liner and electronics on RW) you might get the most accurate AG in the world! (is a nice potencial)
