If I remember correctly, last year the TETRIX folk warned against gearing up drivetrains using the 12-volt motors after a series of gearhead failures. They recommended either direct-driving or gearing down the motors. This was a recommendation for drivetrains, so I'm not sure if they make similar suggestions for other applications. We broke three gearheads last year on a geared-up drivetrain and the problems went away when we changed to a slower design.
I know a lot of teams are planning on heavily gearing up wheels to shoot balls this year (including our own FTC team) and I expect it to work pretty well since the intertia of a whiffle ball is a lot lower than that of an entire robot.  Just in case, we have a stock of spare 12-volt motors and a design that lends itself to rapid swaps.
