It's funny because they say, "It's the last valve you'll ever have to buy," and then you realize, "Hey wait a second why doesn't my gun want to work at low-pressure?" And the valve, the HP LT one, I have the one for Snipers--who knows how well it would work in an HP Autococker because it was designed for Snipers.
They make specific valves for specific setups, but they aren't specific enough in their descriptions of the items, I think. Bold print should be used and disclaimers to let you know what they are used for and what they can't be used for. Because a bunch of acronyms are only going to confuse people.
I guess I'll try to clear things up here:
