Over the 13 years I've been a fotografer, I've had a couple Gitzo CF legsets, a couple Velbon CFs, and a few much-less-expensive models. The Velbons were fabulous for sort-of-normal-weight bodies and lenses (and my friend and his sweetheart still own and love them), but when I bought a Canon 200/1.8 and an articulated arm for it, I bought a Gitzo 1349 (? model #), a tallish 3-leg-section, 1.1"-tube-diameter legset and a full-size Kirk BH-1 BH. That combination was tall enough and strong enough for anything I put on it.
A few years ago I sold all my high-quality Canon stuff, but I still needed a tripod for chronograph sensors and a P&S camera, so I bought a few inexpensive AND cheap communistchinese CF tripod/BHs. I broke a couple but have kept a ProLine CX620B104. Its BH sagged a bit while tightening it and I replaced that BH with another cheap Chinese model, but it still cost me only a couple-hundred dollars, and I'll be keeping it for my chronograph sensors.
I now have coming from B&H a Gitzo GT3532LS legset...http://www.bhphotovideo.com …3_SECTION_SYSTEMATIC.html
This is a member of Gitzo's heavier-duty Systematic series, with 3 leg sections, no centercolumn, a max. height of 59", and 1.27"-diameter upper legs. With a Kirk medium-sized BH-3 BH, all that puts the center of my 6D's viewfinder about 67" from the ground, about perfect for this shortish (5' 8") oldfart.MY
2 most-important requirements for a legset are (A) leg strength so that the legs don't flex and change the view when I merely put my hand on the camera/lens, and (B) enough height so that I don't have to bend over to get my eye behind the viewfinder.
I've loved the Kirk BHs and camera and lens plates and buy nothing but when I'm buying high-quality* stuff. Years ago I tried the first Acratech BH, but the knurling on the knobs, since changed, irritated my fingers, and I could never get used to the different knob positions (compared with those on 'normal' BHs).
Good luck on your quest.
* That's in contrast to when I'm buying inexpensive stuff where I care little about quality.
