And I run 2 bearings with the bevel, which are more susceptible to damage, so just as personal preference I would recommend just regular shimming on the bevel, and then accordingly adjusting the motor height.

You won't really come off any worse?

Then again, I'm just a perfectionist.

Too much to one side will cause problems. But centered is most of the time wrong. It need to protrude in the motor hole just past the beveled teeth. Any more will cause the motor to be too outside and too little of the gear surface will engage. Too inside and the motor will hit the notches to that interact with the ARL.
