This what we are doing. Not because of the slipping issue, but for "smoothness" of rotation. The large Vex omnis have two sets of rollers, offset to the sides for a smooth roll. The small ones would tend to go bumpity-bump as it transitions between the rollers. We thought the smoothness would be better for the encoders.

Very nice! But why such a big green gear? I'd have used a smaller gear and a similar green gear on the encoder. I am curious

Why gear at all? ours is a direct drive set-up.
