Funny you should say that MHes. Exact same thing happened to me kept the "big" keyword combos - the one's everyone optimises for and lost 66% of traffic. Discovered that we'd lost the tail - the 1000-plus product and other pages that rank for a few searches everyday. That's the bit that adds up. Once they returned from being supplemental URL-only, everything went back to normal. And, even the results people optimise for (where spam / distortion is most likely) are very, very good.
