Just my 0.02 EUR here:
I usually carry a Manfrotto 055CL with a 410 head (aparently a typical combination...) I replaced the centre column with a short column for weight saving initially, but now have out a self levelling column on for convenience. Either of those combinations worked really well for me and carried my metal Wista as steady as a rock, as long as the centre column is not extended beyond 30cm or so (about a foot in old money, methinks). The PRO version of the 055 (with the semispherical holder on top) might go a little higher, bun YMMV. The 055 is high enough for me most days, so I don't usually bother with the centre extension.
I have played with the CF version in Calumet once or twice and found to my horror, that the legs seemed to be prone to horizontal flexing when in standard configuration. Not by much but enough to ensure I didn't spend GBP 240 or such on one. Especially as it is only 0.3 Kg lighter than the aluminium version. This was a few years ago and since then the 055CF has gone through a few configurations, so this is probably solved I would think.
I have just picked up a smaller 190CF3 in Ffordes' Manfrotto clearout, and was surprised at the stability of it. It is an extremely light tripod, The vibrations from the stiff legs don't transmit very well and it holds my SLR or Mamiya 7 or my Bronica very well, as long as I don't overdoo the centre column (again). I would not be too worried about putting the Wista on it, if I keep the centre column in. O.o This one will make a perfect travel tripod. 410 head on this one as well
Two other things worth mentioning:
With Manfrotto, stay away from the small rectangular QR plate (RC2) when using LF. I had used one for a long time on my ballhead unit. It does introduce a certain level of "wobbliness" into the setup

It is fine for small SLRs and maybe a light MF but definitely not anything like a LF camera. Lesson learned!
A tripod is a balancing act (no pun intended). You are looking for a compromise between stiffness (for stability) and the ability to dampen vibration. The consensus amongst most photographers is that the best combination for this is still a wooden tripod... Ries or Berlebach are the typical ones here. There is a reason that most surveyors tripods are wood. However, due to the necessity to get the appropriate stability, you need a lot of wood, making the tripod rather large and heavy. Oh, and wood does not deal with water exposure too well, sometimes

If this is not an option, then Aluminium tubing is an appropriate alternative which provides a reasonable compromise. Stiffness is as good or better than that of wood, vibration dampening is not too far off. And the tubing can be reasonably light as well, making this the classic solution for most photographers. It can also withstand water, saltwater, etc with just a little bit of care. In fact, it is usually the steel fittings that go, rather than the tubing....
CF tripods are a "recent" introduction. CF is very light and incredibly stiff in most directions, making this tripods incredibly stable. Unfortunately, this and its light weight means that there is good vibration transmission along the legs and the tripod picks up wind vibration easily

The manufacturers have been addressing this with variations in CF manufacture (introducing a degree of flexibility) by spinning the fibres differently and changing the tube shape to address this and the current generation of CF tripods is actually very nice... But cost often more than a good 2nd Hand Lens
In summary, the larger and heavier yout tripod is, the more stable and the more vibration resistant

In other words: light, stable, no vibration. Pick any two!
There is not much to choose between the main manufacturers (Gitzo, Manfrotto/Bogen, Giottos, etc.), they all make nice tripods with heads that are well exchangeable between them. Wood is nice but bulky and difficult to lug around. Ask Andrew

I know Manfrotto make large tripods (e.g. the 058) which are really nice and stable and have a set of stabilisers between the legs, to limit vibration. Unfortunately, again they are heavy and somewhat bulky. Perfect in studios, though. In fact that is what I used in College to handle LF and MF cameras in the studio.
As advice (if you care), I can only suggest to try them in Calumet or Jessops or similar, and find which ones suit you. I ought my 055 ages(!) ago and it is still serving me very well. The 190CF is becoming a standard companion for me, tough. Usually, I have both in the car. I'm getting lazy, I'm afraid.
