My 8" seems to have gotten more wobbly over time (or I've become less tolerant). It is annoying at high mag, when you have to nudge the scope every 5 seconds to keep a planet in view. The vibrations take a couple of seconds to settle, which does not leave much time to get a good look. Focusing is tricky business too.
I think it would not be a problem if the motion was smoother, less stiff & sticky. I've been looking at doing something with my alt/az axes; fitting rollers / bearings / sliders /grease ???. Haven't made up my mind what would work best. There is also too much flex in the sidewalls of the mount so I've been thinking about making a new mount from plywood, but that would be going against the Minimum Effort Principle.
