I have the Feisol CT-3441 with the reversible legs. When I got it, I didn't care for the telescoping center column, which tended to rotate when I panned the camera, so I cut off the telescoping section and epoxied the extra base from the part I removed to the open end of the large column tube, giving me a solid medium-length column, and this was a real improvement in stability, also shaving an ounce or two. I shaved a little more by removing the neoprene leg covers, which seemed unnecessary for a small tripod. The column still has a base at the other end that can be unscrewed, so I can swap my modified column with the short column.
I use it with either the Linhof Ballhead 1 (49mm base) or the Acratech Ballhead, and have been able to support even an ultralight 8x10" Gowland Pocket View, with lighter wide to normal lenses, and no more than 12 inches of rail.
Those heads are too large to reverse the legs neatly, but I only need to reverse them when I'm packing the tripod in my luggage, so I can take the head off for that purpose, invert it, and then the head will fit with the legset in its original bag toward between the feet of the tripod. With the Linhof head and legs not reversed, it's about 23" (still small enough to fit a large suitcase), and reversed, the legset is 19" (fits in a rollaboard).
It occurs to me that I could use a smaller head without a panning base to eliminate one knob (if you loosen the center column, you can pan with that instead of a panning base), which would make it easier to carry with the legs reversed, head attached, but looking at the heads actually out there that don't have a panning base, they are mostly too small for my needs. One possible exception may be the FLM CB-24E, but I haven't tried it out.
