I did take the advice of Nikonian moderators and members and now use the Gitzo GT3542LS with great satisfaction. However, when it came to the ball head I went with a Kirk BH-1. I'm curious why it did not make the recommended list. I am not trying to be challenging or argumentative in any way, just curious and looking forward to expanding my knowledge.
