I would recommend pivoting on the traction wheel unless you have some serious side support. (See Aren's image where the module is snug between the channel.) We had a lot of problems on the 2010 148 drive with this. Your traction wheels will stay put, but the modules will flex sideways under sideloads. We used chains and had issues with them coming off. May not be such a big deal with belts, though.
