I love my present tripod - a Gitzo GT3530LSV. It's sturdy, light to carry and the twist locks are a cinch to use - it's hands down the only tripod I've ever been completely happy with, and I've had a few.
I also have a Gitzo Explorer which is lighter, more compact, very sturdy, even with heavy lenses. On the face of it, it's the ideal all round tripod, but it has the old style twist locks which tend to lock up. It would be a stretch to say I hated it, but it drives me nuts compared to the other. :nuts:
You just can't put enough time and thought into purchasing a tripod - if you really don't like it you just wont take it. :shrug:
