We had some trouble shifting the Dewalts and made no use of 3rd gear last year, so we were a bit slower than I'd hoped. As always, the game may change what we put into the drive, but if we can avoid pushing matches again, we'll probably stick with 1 CIM per side. Similarly, it's shown with four traction wheels, but we may again use just two and put omniwheels back onto the corners.
We expect to have our hands full with the new cRio system, so anywhere else that we can remove complexity, we'll do it.

I would never mount bearing blocks to 80/20 using the T-slots. They slip way to easy under the strain that is being placed on them. Drill through the 80/20 and bolt them right into it.
Thats just my opinion.
