There's been a lot of broad, out of hand, dissing of tripods with center columns. Gitzo, Manfrotto, Induro and others make some excellent tripods with center columns. I use the Induro C414, 8-ply, carbon fiber tripod, which includes a center column. Induro recently replaced the C414 with the CT414, which has a couple of minor differences, but the same mechanics. I'm mounting the Canon 7D with the EF 500mm f/4L IS, EF 1.4x Extender II, Arca-Swiss Z1 ballhead and Wimberley Sidekick, for bird and wildlife photography.
I would suggest that the center column be used judiciously. I'm 6' tall and set my Induro up with the center column fully down and locked so that the viewfinder is about chin high. At this height I can shoot at the ground or at medium height in a tree, up to about 20-degrees, by stooping just a little. When I need to shoot higher, I raise the center column about four to six inches and can easily get up to about 70-degrees elevation. Most of the time my column is all the way down and locked with the Induro's very substantial locking nut. Raising the center column a few inches is much easier than adjusting all three legs and re-leveling.
How stable is the Induro with the center column raised a few inches? Very stable. Changing the column height is going to change the resonant frequency at which the tripod transmits the shutter vibration, but that change is very small. (All tripods do this, but heavy wooden tripods probably damp the resonance the very best). Keep in mind, the shutter speed is often about 1/1000th second. Still, even at slower SS the stability is comparable to when I extend all three legs further to get to the same height.
If you extend the center column 12" or more, then you'll greatly reduce stability. In fact, with a heavy lens you'll be in danger of the whole rig falling over in a strong wind. Don't do that. Most of us aren't tall enough to raise it that high anyway, but if you shorten the legs up, then anyone could do.
One recent pontification said:
"They are unstable, changing your tripod into a mono-pod.."
That's simply untrue, at least when used sensibly. There may be some inexpensive, unstable tripods with center columns that are unstable, but I'm talking about high quality tripods, appropriately sized for the lens and camera in use.
The following complaint was also made recently:
".. and they prevent you from carrying your big lens in a manner that will not damage your shoulder over time."
I don't have this problem at all. To carry the tripod over my shoulder (with the camera and lens attached), I put the column all the way down, open two of the legs a few degrees, tip the camera and lens down around 30-degrees and put the rig over my shoulder at about 45-degrees with the tripod resting on my shoulder just below the ballhead, where the legs are spread.
I've have arthritis in my neck from a football injury that causes the trap muscle on the right side to be in constant, low-level pain. My left shoulder was replaced after a mountain bike accident. Despite this, I'm comfortable carrying the tripod and camera/lens for long distances in this mode. For a really long haul, I'll dismount the camera and carry the camera/lens by the lens-foot and the tripod either under my armpit or in the other hand. My "linebacker build" and low pain threshold may account for my tolerance, but I don't see how the center column even enters the equation.
As for those that wonder how I dare buy an Induro instead of a Gitzo, I read the horror stories about both. Apparently they both have introduced design flaws to the market and both have spotty warranty service. Having read all that, I went down to Denver Pro Photo to compare them in person and chose the Induro. Both seemed to be relatively high quality. I didn't use an online retailer, as I typically would, because of the uncertainty and wanted to see for myself. Of course, once I had availed myself of my local brick and mortar retailer I felt compelled to reward him with the sale.
