Thanks gentlemen. Much appreciated. I also saw an interesting evaluation of the Flip Lock from the guys at Luminous Landscape. It was embedded in a review of the Cube.
Also part of that review was an off topic mention of the ball head from Photo Clam, another Korean company that makes a very good copy of the other well known Korean ball head, Markins. He liked the Photo Clam so much he sold his Markins heads. Simply said it worked better with no slip.
I think in the end, you just pick the one you like for which ever reasons and go with it. At a certain level they all seem to function and work the same and it seems to me, looking in fairly objectively as I make my choice, evaluating ballheads at a certain point is just an exercise in splitting hairs.
