I've heard others say that about wooden tripods, I do have two but the first a Gandolfi is awful in terms of build quality and the second is a pro-TV/35mm cine camera tripod built like a tank and very heavy.
This is why I think it's about knowing your own equipment. These days it's rare I use 35mm or 120 SLR's although I've bought 2 pre WWII quarter plate and two 6x9 SLR's recently but they seem to have very little mirror slap compared to later cameras, strangely. The mirror moves as you press the shutter and isn't governed mechanically, the shutter only tripping once it's up, so you move the mirror mechanically and there's no slap.
With all equipment there's no hard and fast rules, it's up to us as photographers to find what works best as individuals.
Absolutely agreed about knowing our equipment, Ian. The Berlebach is a wonderful tripod, unless you have to travel. It's got quite long legs and won't fit in any suitcase. But it's comparatively light and built very well. 35mm tripod mounted shots with my Pentax SLRs (which don't have mirror lock-up), show really amazing clarity in large prints, regardless of shutter speeds being 1/60s or 2 minutes.
