The best 'tip' is to reject the ballhead totally now as an outmoded device.......to do it's job it has to be a big lump of metal and is severly limited in it's functions. I used to own several ballheads but have not used one in years, not since video heads got nifty, clever, cheaper and considerably lighter..... In addition, a small video head allows scanning of the scene to determine composition and exposure etc which is not possible with most ballheads...also, should some video be required for panaramas etc then it's easily done.....
My favourite head is half the weight of the ballhead it replaced and is a Manfrotto item, can't remember model but it's a few years back now and I made the knobs smaller and better with the aid of a hacksaw......
