Doesn't matter much in DEC as you can be North or South heavy. The only concern on a big newt is close to the meridian imaging close to the SCP when you have weight shifts with a heavy camera when the focuser is not pointing right up or down under the scope. You get off balance in RA as soon as the scope goes past the meridian and the camera adds to the weight westwards.
AHA! So many little jigsaw puzzle pieces fall into place just now!

At this moment, I understand exactly what I have observed with my 8" and the bad tracking in those critical positions. I did read about those effects but it didn't really make "click" and I couldn't apply it during my sessions - until now.
Super!
