I was kind of wondering this myself. I'm on week 4 and I foresee myself continuing another six weeks. Honestly, I think this method may take me through the summer season at least. I was using HPM for 3 phases and saw great results and I think this was a good transition.
For me I think the real question is how to I incorporate this method with some of CT's other methods without "Frankensteining" anything. Reason being, this split of Shoulders / Squating and Chest / Deadlifting has actually worked better for me than the HPM split. I actually got a compliment this morning on how much bigger I'm looking lately. Sure I've gained some size but my shoulder strength has really improved.
CT said these complexes were more body composition oriented, so I'm really hoping he comes out with a more strength oriented Complex methodology.
