Thanks for the feedback - I hadn't thought about the 'balancing knob' theory, but it seems to make sense as I need to make a major adjustment for little gain.
On the use of the counterweight; my 12.5 has a groove/channel cut in the back part of the arm tube for the c/weight locking screw, so I cant off-set it (it locks it into a central position). That's the most frustrating part, because all the commentary is about using that to set the azimuth.
I might see if I can remove those 'balancing knobs'
