Not a fan of those hold down to vent dumps...

Also Kane can you make sense of this;

9.7.1 Custom Components
Custom made components, or parts operating above the suppliers maximum working pressure, must be
Independently tested and certified at 120% of the maximum system pressure available at that point.

Key word being independently as mario and team mute have said they test there equipment... I don't blame them if they have the gear to do so them self.... But to comply with the rules wouldn't they need a 3rd party to certify there gear? Not just them... But anyone running a compressed gas system be it air or co2, or can we all say we've tested our gear to 120% and give our self a certificate?
