I'm trying to decide on a new setup, tripod, & ball head. I've pretty much decided on a Manfrotto Mag Fibre 190MF3 tripod, at least I think I have. The ball heads are another matter. I'm kind of leaning towards the Really Right Stuff BH55-LR head, but the Kirk BH-1 head looks good also. I realize I'll need to get some new "feet" for my lenses, regardless of which head I get. I'm also considering the Wimberely Sidekick. If anyone has or uses any of the ball heads mentioned, please respond back with your insights.
