Hi guys i'm looking at getting a new tripod in the $500-$700 range, problem being there is so much choice in this range that my head is spinning.
I've already got a compact travel tripod, so size and weight aren't real issues. What i would like is something that is sturdy, with a fair height range, and able to carry a reasonable weight (7D+grip with 100-400L).
I assume that carbon fibre is the way to go?

Here are some i've looked at;
Benro C2970F3
Benro C4570T
Vanguard Auctus 323CT
Vanguard Alta Pro 284CT
Silk Pro 923CF-3

Thanks Kipp
