I have the Manfrotto 055 tripod and like it a lot. I really like the lever locks so when I bought a Monopod I got the B680 and like it even more.
I need a heavier more solid tripod than the 055 for table top work and longer lens, mine even though rated at I think 15 pounds vibrates pretty easily.
In the heavier tripod I'd like it to be metal like the B680, weight is not an issue but ease of use is. Also if it has a rock solid center column it would be a huge plus.
I've tried looking through BHPhoto and just get kind of lost.
My local store has a Gitzo that is very heavy metal but I don't like the twist legs and it's cumbersome to use which has me wishing for a center column but one that is also very heavy duty. Something you might put a view camera on.
I'm using an AcraTech ball head right now and is seems to be quite nice, otherwise I think I'll go for the large RRS ball head.
