Has anyone else dumped their ballheads in favor of a better system? I've gotten tired of mine from a leveling perspective, which I usually do by groundglass. I also generally shoot with the camera above my head which makes a bubble level on top impractical. In video production we level the tripod and that's that. I'm t hinking of maybe doing the same and getting one of those Bogen one way tilting h eads, and panning with the center column. Problem is I need a bubble level for m y tripod.
