Ummmm yep, thats what I meant - the contract side is smaller so less force, but
wouldn't that also mean it contracts faster because it needs less air? Just like
the small cylinders expand/contract much faster than the big ones because of the
much smaller area?

less friction, combined with the fact that they have much smaller cavities.  The
old large single acting pistons expand/contract much faster than the new large
double acting pistons because they have much less friction.
