thks everyone for your input.
not to look at the price 1st because I doesn't want the price to affect my decision, if I going to get 1 good Ballhead which last me long enough, I willing to go for the best one for me.
Below comment is just my personal opinion.
think RRS is pretty out, I prefer not to get it online, hate the shipping cost and the waiting... If i am going to get RRS, I rather go for Arca-swiss Z1.
never come across kirk... where can i get it? and how is the price like.
kangrinpoche spec, price, and feel look good somehow I do not prefer China product and I don't like the website, it just don't give the product a expensive feel, even B&H, Amazon don't carry their product, above mention do not give me any confident in it... (believe a few of you guy feel the same as me)
Arca-Tech look cool in design, I know that it is a very good brand for tripod head, I alway have a believe that it is either design or practicality. But of cuz it will be in the list.
As for Gitzo Center ballhead, GH2780QR, price, weight & brand is right and it even have spirit leveler on the plate and neck but max load is not too good, only 14KG, of cuz, I may not need such a heavy capacity ball head as I may not have such a heavy setup, the more buffer the merrier isnt it? heehee
Markins M10 look one of the best among all to me. with spirit leveler, good comment from all user in CS, price is decent. If it come with a standard plate, I will go for it, at least it save me $85. Think i have to nego with TK...
sorry to everyone if some of my word is harsh but I prefer to speak out so everyone will be able to understand how I personally feel about these ball head.
