With the 39x, there seems to be two camps. Valve stuffing, and the opposite 2X.3x,6x etc.
I seem to have found myself in the X camp, though counting pumps can be distracting... time to add a gauge and more volume!
Which fire do you stare at?
While i am very much an airconservationist, i also recognize simplcity......
My AC397 to 12 - 14 pumps to charge, and 4 or five to bring back to full charge. 5 pumps is much eaiser than 8.
but runnig the 1377 to 10 pumps doenst seem that big a deal.
I think I stare at the Efficiency fire. Wring every bit of oomph you can from any given platform.....
