Knowing how uncommon 3.5oz tanks are, which makes it difficult for fill station operators, exactly how difficult is it to fill that 30g?
What about Gameface Air source? https://www.gamefacepaintball.com/air.html
Has anyone ever tried using it with an on/off? And, has anyone tried refilling it?
I'm not intending to hijack this thread in regards to my question, but since we're on the subject of small tanks, I thought the Gameface product would be a good comparison.
