I have heard (but never tested) about getting better efficiency from the hardline by running a copper wire inside the harline to take up most of the volume. Since you are using a pump, flow will not be an issue.

B, the microline fittings are rated much higher then the macroline.

I have forgotten my physics, but something about the pressure pushing against a smaller circular width? For both the fittings and line?

Not that I would use either, but I've never seen microline blow, while I can't think of a single weekend where I DIDN'T see a macroline blow.

I have heard that as well, but I am fairly certain it is not true.

I buy most of my fittings and macroline from a pneumatics/hose supplier. Per the manufacturers spec sheet, the fittings and line are rated at 1175 psi safe working pressure. ( I made them show me)

They look a litle different from the typical 90 though, and the macro only comes in black with white writing on it. It has never failed on me though. Ever, in 5 years of playing.

F=PA

There's more surface area in the macro for the air to push against. So at the same pressure the larger tube is under a lot more force.
