Just to let you know that I have now recieved my AS B1 Ballhead with a brand new RRS assembly mounted on it. It looks solid !!!! .... and with a bubble level to boot !!!! It took me precisely 11 days to get it to USA and back to me here in Bhutan. My friend in Portland handled the whole thing for me ... and I am told that the person on the phone at RRS was very helpful and knowledgeable. He just shipped the assembly to my friend and she simply changed it for me and sent it back.
Thanks for your advise.
