Oh Lee, today I was in the shop, finally buying a 475 tripod... guess what I've seen there? The same ballhead as I have, the same controls, the very same catalogue numbers, but... the ball is made from something like a phenolic resin! And my head's ball is full metal, very nicely chromed and polished. Is it an another example of Manfrotto's cowardice? Really, I can't get it when the same catalogue # products are sold in two fashions, with a completely different working part - of course I'd never buy a ballhead with plastic ball! The store managers don't know if this head was available in metal-ball variety, they said they were selling only the ones with plastic ball. Now I understand why my head lacks this stick-start quality described in many reviews around the net...
