Yes...This!
We determined that we needed 12" of stroke for the 2014 shooter. We started with a single 1.5" bore cylinder, but needed either higher pressure than the 60# allowed, or more flow than one solenoid would provide to get the distance we needed. Because the pneumatics rules specifically prohibited plumbing multiple solenoids to a single cylinder - we ended up going with three 3/4" cylinders operated together, eacj with one of the above linked solenoids. We also plumbed an individual Clippard accumulator to each solenoid (working pressure) to have an available volume of air very close (in addition to the accumulators we had at storage pressure). I think the tubing length was less than 3" I'm not sure how much of an impact this had, but it was easy to do. When we hit the fire button, the cylinder action sounds like a gunshot.
