Slewing maybe, but most imagers slew once and done for the night.
My C11 assembly is now 26kg. I can tell you that inertia with lighter counterweights down the shaft affect the tiniest corrections during guiding. Go heavy and as close as you can from the RA axis to avoid unwanted oscillations and I'm not talking about backlash.
