I would strongly suggest acratech for your ballhead choice, yes they are pricey, but the machining is first rate, excellent design, and they look to be a many year purchase. Acratech made their bones doing precision machine work for nHra drag teams. And spend the $ for a model with a built in level on the base. And a little customer service story, the little bubble level fell out of one of mine, probably due to the fact that it's on my pickup tripod, and i tend to get lazy and not take the time to secure it in the gun rack as i should, i called them up looking to buy a replacement, the owner happened to answer the phone. He said that should not have happened to one of their products, so he sent me not 1 but 2, at absolutely no charge. Now that's the way to take care of the customer, and one of the reasons i recommend their products
