Any particular reason for using Mini-CIMs over CIMs?

2 Cim 4 Wheel Drive.

4 CIM, 4WD wide configuration Kitbot, KoP wheels.

6 x 4" VersaWheels with 3/32" center drop in a long configuration. Laser-cut sheetmetal. 4 CIM VexPro Ball Shifters. Like everyone else we anticipate a lot of pushing matches this year moving back and forth to and from the feeder station.

Vex Pro Drive in a Day, 6 x 4" Vex Pro Performance Wheels, Roughtop Tread, 4 CIMs in VexPro Ball Shifters, 14/6(ish) ft/s.

We're using one CIM for our shooter and two for our climber, so we couldn't put four of them in drive. We didn't find any significant decrease in drive performance between the full sized CIMs and the Minis, so we stuck with it.
