now that I think of it, you are better off using a larger diameter cylinder at a lower working pressure than you are using a small diameter at a high pressure

because the compressor can pump more volume of air at the lower pressure - so that approach would let you cycle the cylinders more frequently.

if you are running larger cylinders at 30 PSI then the tanks can drop to 32 psi or so before your applied force starts to drop - and the compressor can get more volume at 30 than at 60

if you are running them at 60, then the compressor will start to fall behind at 62 psi,and will have a harder time keeping up with the demand.
