They're actually really nice transmissions, they just get a lot of bad rep.

I'd suggest using two globes direct driven to some skyways. We use those in our offseason competition a lot, and they work great.
we only managed to get 1 globe you should have seen the people in the workshop when our teacher said go! i grabbed 2 cims, 1 big cim, 2 fp. im probably going to make a custom 1 speed gearbox, 2 speed if i have time with 4 inch wheels, do you know were we can get some cheap 4 in wheels.
