> So, for the bearing size and position what should I assume?

Like Chuck, I  use the half way point between the lightest and heaviest
eyepiece as the balance point. Large bearings help, as they increase the
friction without compromising smooth operation. In your case I would use a
bearing diameter of 1.6-1.9x mirror diameter, if you can..

If it will still tip with the 20 mm Nagler, well let's attach in this cases
a counterweight at the back.
