There is a fine round-up of several ball heads, compiled and tested by Mark Banas, over here: http://www.dpreview.com/articles/8192473209/battle-of-the-titans-top-ball-heads-tested/4
I'm happy to report that FLM was found to be the most stable of all the ball heads tested.
Enjoy, it's a very good review of most of the major ball heads in the market today.
