Well first let me say, 41 to 38, talk about a nail biter... Congrats to you Texas folks!!! Anyway, I have decided to keep my B1 since RRS has pretty much taken them off the map. It is still a great ballhead and I am glad I have it, but since I won't be able to get much for it, if I can even sell it at this point, I am going to just add a sidekick. I already have purchased the RRS replacement foot for my soon to arrive 200-400 VR and would greatly appreciate seeing a photo of the 200-400 with a RRS replacement foot on a Wimberly Sidekick. I am just wondering how far off center this foot makes the lens over the center of the head attachment. I remember reading a thread in which someone said they have this combo but could not find it, so if you have it and would be so kind, it would be greatly appreciated.
