why would you want more pressure on the retract then the extend. In pneumatics like we have there is no real "speed control" or "stroke distance control" that we have by limiting pressure input on different sides

Well, you're 1/2 right. True, you can not regulate stroke distance with pressure. You CAN regulate the speed at which the piston moves (and it can be different extending and retracting) with the small fittings that have the white knobs.
You also CAN create a very simple multi-positioning setup with parts from the kit. This will allow you to extend a piston part of the way and stop.
You typically do this by using 2 selenoids. One double, and one Single.
We did this last year, I can't entirely remember the setup.
But It's not difficult, or space consuming or anything
