I've been using my old, aluminum Bogen 3021 since Mike Kirk modified it in the mid-1980'S. But it weighs a ton and isn't quite tall enough for my needs (i'm 6'3 and work in the mountains, so lots of uneven terrain). In researching carbon fiber tripods I've found several that will extend to 66" or so, but the spider won't allow the legs to spread out flat for ground-level work. I don't want a center post (not much of one, anyway) to get in the way of low-level work.
So here I am, asking for suggestions. I have often read that no tripod needs to be taller than 5'. That is utter trash, so please, don't go there. :)
