That's good news. My interest is in building full-built models and not
the technic see-through style efforts that I usually see the pneumatics
used on so it'll be important that the cylinders are capable of moving
the combined weight of the bricks.

I followed the link that Tobbe had pointed out and will try seeing what
I can do to improve the flow of my one "gunked" cylinder. Hopefully I
can bump it's performance up to the standard of the other.
Thanks for the help!
