Our team tried doing a direct drive with the CIM motor but the ball did not go very far. I remember reading that a 2.7 to 1 gear ratio works best but I can't be sure. Any ideas?

The gear ratio depends heavily on the diameter of your end effector, assuming you're doing a roller/wheel shooter. Direct-driving with a CIM to a 1" roller is very different from an 8" wheel.
OP, care to provide any details? My team's experiments show that you should find the exit speed you need for your range, assume the ball will go 60%-70% of your theoretical tangential free speed, and gear accordingly.
