I've read that just about everyone finds the AZ on this mount so tight it makes it nearly impossible to do a nice smooth pan (as do I).
My solution was to buy a relatively inexpensive Feisol PB-70 Panning Base. I mounted it between my tripod and the mount. The AZ lock on the head stays locked and I use the Feisol to move the mount in AZ. It has a slightly dampened movement and can itself be locked with the panning base lock knob.
Now I can use this nice little mount in "manual" mode when ever I don't want or need the goto function.
If anyone else has tried other solutions that work I'd like to see what you've come up with.
