Once again i find myself say "what took me so long?". I said screw it and picked up a Joe B. Guppy. When I opened the box I was glad I did! It is beautiful, nice long hose with double disconnect. 2 gauges makes it EZ to know what pressure is where. It's set @3000 psi I think, but easily stopped @2600 keeping close to the sweet spot. Would be silly to waste 400psi till you got to the flat spot in your curve. And Joe is a real gentleman. If I got the air Venturi I would have got sick from the lack of helpful features.
I work outside and it was 100 degrees in the sun today. If I had to pump there is noway I would have been able to shot 120 rounds in under 1/2 hour. And the tank fill spot is 2 miles from the range. Which is all on the way home from work.
