Hello: I'm new to nikonia and was wondering if I could get a little advice. I've ordered a 400mm f2.8 (my first pro lens) and am now wondering how is the best way to support this. From reading many of the posts here, it seems clear that a Gitzo (Series 3 or 5) tripod and a full Wimberley Head is the way to go. But I'm open to suggestions. I'm leaning towards the Wimberley Head because I've read that John Shaw has a lot of respect for the it and I've got alot of respect for Mr. Shaw. But I'd like to hear any opinions people may have on some of the heavy duty ball heads.
