We're of two minds with this. One the one hand, we really like the idea of highlighting the whole wheat pasta and treating it as more than just a substitute for white pasta. Serving it with the right ingredients might be a way of convincing skeptics that whole wheat pasta is worth trying. Their recipes for whole wheat pasta tossed with aromatic olive oil and fresh veggies do sound fantastic!
On the other hand, most people do treat whole wheat pasta as a substitute for white pasta and use it in all sorts of traditional dishes. The flavor combination is different, to be sure, but not as off-putting as Cook's Illustrated seems to be implying. We resist the idea that only one particular sauce can be used with whole wheat pasta.
