I know 1114 uses #35 chain on their tankdrives because they run exact center to center and avoid tensioners. They also try to match their drive wheel diameters to the pitch diameters of the wheels (not really possible on most WCDs). #35 is definitely overkill but overkill is nice to have in a drivetrain. (low maintenance too)

Tangentially, I want some enterprising company to makes usable sprockets for bike chain. Bike chain is stronger and lighter per length than #35, more resistant to misalignment, more readily available and has readily available and awesome chain tools for relatively cheap. Also comes in cool colours.
