Cim-Sim gearbox for shooter questions

[RoboCat2005]

I thought I snapped a picture of you guys. I've attached it here. I love the bump travesal sstem, by the way. Questions I can't answer from the pics:
How many and which motors into the CIM-sim?
How many and what diameter shooter wheels?
How much compression are you running? (How much space is there between the wheels and the hood?)
Are you running the motors at full speed when the ball dribbles out?
What, exactly, do ou mean by a horrible lag of the motor when a ball goes in?

Thanks we worked hard on the system for getting over, we based it on the NASA Rocker Bogie system.
To answer the questions:
-2 Fisher Price motors
-Started with 6" now has a 4" in it
-With the 6" it had about an 1.5" almost 2" of compression, although it happens early and the exit is a little less then at the beginning.
-it bogs the motors down quite a bit as the ball drops in
-Each motor is hooked up to a jag each and the motors run at full speed when the ball is introduced.
