Why Adding Friction Doesn't Solve Balance

Some claim that if you add enough friction into the altitude axis of a mount, then you do not have to balance your telescope.  This is a bad idea.  Here's the physics:
No amount of apparent "smoothness" during longer sweeps can overcome the jerking effects for small centering and tracking adjustments. A mount which resists shifts in balance is a mount that resists turning!  That's the physics.  Hitch mounts eliminate these problems by making complete, adjustable two-axis balancing easy -- and by employing true low-friction bearings to make turning forces predictable, intuitive, and controllable.
