These would be really useful in a manipulator because of their relatively high power density.

I agree with this point with the caveat that it really depends on the game piece. Sure, you can pick up any game piece using this motor on a roller when you're sitting still. However when you're in motion the roller needs to move at a speed
greater than your robot's speed, otherwise the game piece will be kicked away or forced to slide with the bot (which greatly increases your chance to be defended against). Combine that with the needed torque to pick up the game piece of the year and you should see that there are many years where a small intake motor like this just isn't feasible. Use the "Intake Mechanism" tab of JVN's 2008 Design Calculator.
The conclusion I've derived is that with a 20:1 gearbox this motor was ideal enough to pick up the tubes in '07 and 1-2 poof balls at a time in '06 if your bot drove 6ft/sec or less. I agree that they're great power for the small size and weight in these years.
