I'm using chain simply because it's not as wide and thus reduces the cantilever needed.
I'm glad you asked, though. I slept on it for a day or two and realized that the only reason I was running chain on the outside of the rails was because it was on the opposite side of most of the wheels. After thinking it through, however, I realized that the center wheels are probably the WORST wheels to add extra cantilever to. If the shaft were to shear despite it's factor of safety, we'd have to rebuild the entire gearbox with a new shaft. If one of the shafts on the outer wheels was to shear, it'd be much less difficult to change out. The center wheels also experience the heaviest loads and impacts.
I made the switch to VEXPro 2 CIM Ball Shifters due to their stock encoder mounts and reliability. I then stole 973's WCD modifications for the ball shifters and ran the chain inside of the rails. This significantly simplified the exterior of my bot, allowing me to easily mount the standoffs that make my frame perimeter.
You'll also see that I switched to WCP bearing blocks and forgot to add my battery holder.
Here's the result. Weight is now about 36lbs.
