Ok. Well I've just ordered mine earlier. I think one reason NP markets their products as you say is to ensure that people get the desired performance out of their products, and the only way to do this is to warn people that not using homogeneous parts could be a problem.
I don't see why/how it won't be really good, especially when I'm paying top dollar. We'll see soon enough.
