Fine balancing is not regarded as that important per the manual.
Its also dead quiet when tracking. When slewing at 600X its not that loud either. At 1200X its louder but not outrageous. It does sound like the motors have plenty of grunt which is reassuring. There is no movement in either axis when you give it a slight push. No wiggle, nothing. Amazing. The whole unit comes across as ruggedly accurate and precise.
Its also able to be upgraded at home with absolute encoders ... This gives you back the home position which is probably one of the best Software Bisque features of their mounts ...

Greg, there are sets of little black clutch knobs on the RA and Dec. Yours must be very loose, or finger tight only? For heavier loads, AP recommends that you tool tighten - but not excessively.
AP also have plans for homing-limit switches on the 1600. It's a kit that you bolt on. A fraction of the price of the encoders, but still giving those homing and safety stop features that we love on the SB mounts. See the 3600 page - they've been out for a while on that mount.
