I'm wondering if anyone who has experience with both can offer some insight, and some general drive-train advice.

My team would like to switch to a shifting gearbox, and I'm trying to weigh the feasibility of the task. From the images on andymark, the toughbox and supershifter look similar enough, however our robot is pretty tightly packed, and so any changes in the footprint of the shifter (dimensions, where the motor sticks out, etc) could be a deal breaker.

Also open to information on the Vex Ball Shifters.

Adding the pneumatics won't be a problem for us, and the programming portion is also fine; but from a mechanical standpoint, I don't want to throw down several hundred dollars only to find out they won't fit.

Gearing ratio suggestions are also appreciated (we're using 6" high grip wheels,4 wheel chain drive, with 1 cim each side), right now we're geared really low, and the kids love it, but the lack of speed when we need it is troublesome.

I've also considered gearing the robot up a bit and throwing another CIM in to help offset the gearing, will that give us more speed with the same push?
