Shifting is a great thing for 6 cims, as you can use the low gear for positioning the robot for accuray, and the high gear for moving at 18fps+.

for such a light test bot we don't really need to much power. Its only about 25lbs. So we'd be wasting a good cim if we had 4.
The only purpose of this bot is to get drivers practice and prove a theory that one of our mentors had.

FYI driver practice is generally somewhat useless on a system with radically different drive characteristics from a finished product. If you are giving non-drivers a chance to practice driving something, that is useful though. And building prototypes is ALWAYS useful!

Driver practice on a non similar bot during the season is not as beneficial (but practice is practice), however during the offseason any practice is beneficial, even if it is on a robot that is nothing like your in season robot. Just being able to learn the control layout and get comfortable driving is a huge benefit.

I would suggest adding a weight box to bring it up to competition weight of 150 lbs with bumpers added so they get used to size. Then test with different motor configurations while driver training. You will gain more from this than drivers just getting used to controls. Your programmers can use this platform to test autonomous modes as well. A light robot will have very different characteristics than an "up to weight" robot. Also, corner braces to stiffen the chassis from racking, along with a shear panel or belly pan.

Or we can just throw a shooter on it
but transitioning from a 4 wheel direct drive to a 6 wheel chain drive is different.....
