The 'issue' with hubs like the BHS (Bitex) and Rotaz as is that they use the same hub for both campy and shimano with a simple switch in freehub shells and the dual purpose set up doesn't leave much room for spoke spacing. The Rotaz will give you more even tension but at the expense of lateral stiffness as it doesn't have much offset to either side. But as you point out the American Classic has the same set up and DT hubs are similar and you don't hear a lot of complaints about either. The key is to take your time to get the tension high and even and the wheel should be good.

But using DT Revolutions on the NDS and Competitions on the DS will allow for a small increase in NDS tension and using something like boiled linseed oil or the Wheel Smith prep will ensure that the spokes don't loosen.

For what it is worth I have the White H2/H3 hubs on my high mileage training wheels and built a set of climbers with the bikehubstore Super Light rear and Wide front. I also built my wife a set with the Super Light rear and Ultra Light front.

I find the Dati hubs intriguing and will probably build a set using them with carbon rims, but I haven't seen much feed back on them yet so I haven't made up my mind.
