Not entirely true. I spent last weekend testing the plausibility of pneumatic angling. By using a dual solenoid, and 1 spike controlling it, im able to get infinite variation with no lack of strength.

The solenoids two red leads go to M+ and M- of the spike, the black going into a splice on the ground side of the spike. By setting the the spike to full forward (12 volts on both pins, 0 pot. difference) the cylinder hold position due to equal pressures. I can then simply set the spike to forward or reverse to raise and lower the piston, having it default back to holding. On a 1"" bore bimba piston, i cant move the shaft at all. Flow control valves on the piston allow me to control how fast it moves up and down.

I may link a video if i get the chance on sunday...
