I don't know anything about Giotto tripods.
But I recently did a whole lot of net "research" when I was looking to buy a ballhead for my wife to use for macro photography, and ended up with a Giotto MH7001. I have used ballheads for the past 10 years, but the Uniloc head I use for my LF cameras is just too big and heavy for her use. Besides, I'm using it myself
The head will be used on the Uniloc tripod I bought once upon a time - great for macro, not great for a 6 kg LF camera
