Thanks to the very informative discussions recently on tripods and ballhead selections, I finally bought a Gitzo 2540, an RRS BH-40, L-plate for my 30D and a lens plate for my 70-200.
I just wanted to express a word of gratitude to JohnJ80, Lightstream, and Prydain in particular for their knowledge, experience, and willingness to help the rest of us make informed decisions.
Many thanks, gents.
