First and most important (this was brought to light by other shop's comments to us). The bracing angle which is what is really important, is more than sufficient on the regular SONdeluxe. Think about it, wheel trouble is typically always on the rear. We never ever have had a problem with a front wheel. But on a high dish wheel, such as Campagnolo 10sp, the rear drive side flange can be less than 18mm from the flange center - it is actually approaching 16mm if I recall correctly. So the 25mm on the front wheel is way beyond that. It is 50% farther out from the flange center than a modern Campy drive side rear!
Now for heavy riders on a loaded bike riding off road, we can see why the higher bracing angle of the wide body hub can help in theory. But we've never had a customer report a problem on a front wheel. So we are bit skeptical.
So for the typical rider, and for my own bike for example, I'll be reaching for the regular SONdeluxe. If I'm building a bike for a heavier rider, or one riding off road extensively and especially if loaded, this hub is a great new addition to the Schmidt line up. But as I look over our roster of bike builds at the shop at this very moment I don't see any where the wide hub seems to be a better option. Now I do know of a couple coming up later on where this hub might make sense. But those are more the exception.
