Re: Two pressures?
If you can find a place that the latex tubing will pull enough that it will extend the cyclinder when it is pointing down and using the non-pneumatic air extension you can make Ken's spring way work. If not, route all exhaust from you cyclinder to a single solenoid with a stop on one of the output and block so you can control the stroke length of the cyclinder. You look like you could have the cyclinder partially extended to begin with and a least cut down on the wait for it to lift. Or you could lengthen your arm and purchase a shorter cyclinder. A 16" would do the job or even a 12" or 8" and would reduce the air needed. You lose height gained but an inch or 2 feet both get you 50 points. The one just works faster. I would add the second accumulator and make sure to reduce all tubing lengths. PM me and I'll give you more info about the single solenoid.
