I live about 500 miles north of their office.
Their shipping sucks. I ordered a center column for a Gitzo I bought at RRS the day after at B&H, which is in NY and I'm 3300 miles from them. I got the center column two days before the tripod, 500 miles away.
I also bought a Gitzo LSV tripod with the BH55 head and plates for my 70-200L and 5D.
The set up is impressive, both pieces being very impressively built. However, the BH55 is no pack head. It's very heavy. In fact, the Gitzo LSV with the BH55 and the Gitzo center column are a rather heavy combination. The tripod and center column weight about 4.5 lbs I think, which is really light, but that head feels like a canon ball. They should think about making one from titanium.
Also, as others have pointed out, RRS and Gitzo are very expensive. I too dropped 1575US on my tripod kit. Hopefully it will pay for itself by being trouble free for the next decade.
I am troubled, if true, that the Arca Swiss has a better coating than the RRS head.
