I'm not familiar with your system, as stated I have an Astro-Trac. What I did find trying to use the unit with 2 ball heads is it's near impossible to set the latitude on a ball head. Instead I was lucky enough to have a friend selling a studio gear head with 25Kg payload capacity and bought it from him cheap. For the primary camera mount I'm using a heavy duty ballhead also rated at 25Kg.
I have fitted a Polemaster adapter I machined to my Astro-Trac but haven't had the chance to play properly, just once and I messed it right up because of my unfamiliarity with a few pieces of the equipment (all of it basically) but it eventually will serve me well I'm hoping.
Start with a reasonably level area, I was playing in my sloped back yard and it caused all sorts of issues because I levelled the gear head not the tripod which meant after any rotation it was no longer level,
stupid old man mistake, it won't happen again.
With my load capacity with good alignment I should be able to shoot with my Megrez 80mm scope. The Astro-Trac only gives 2 hours of driven tracking before it has to be reset but that's a lot more than I currently have, 30 odd seconds without tracking. I'm hoping eventually for some good results.

Not so much a head as per your device but they are supposed to work well.
