I found this out. I bought five boxes of Zamors (50 balls) that were going
cheap when the LEGO store in Kingston, UK, was closing down. Unfortunately,
they're too big to go through something like the 2x2 shaft of a ball pump. I
had to buy some footballs at Bricklink prices.
They'll work on something like the wave bed, moving steps or scooping modules,
but they're not going to work the same on something that uses narrow channels
like the ball pumps, catpults, spinning-wheel launchers or staircases.
You could easily have two loops - a smaller loop for Zamors and a larger one for
footballs, that share a common stretch of modules. Those modules would need a
higher throughput though.
Sorting them is easy - just two beams 2-studs apart. The Zamors will run along
the top and the footballs will fall through. Of course there are probably far
more elaborate methods possible...
