Interesting routine. I've copied it and saved it as Kuyt's Killer 6 day. If you survive and thrive, I will try it out one of these rotations.
Funny, but if I were making an over the top routine to bring up my particular weakness, which is my back, this routine seems perfect as it hammers your back and would perhaps be perfect for me. You, however, already have a pretty damn strong back, it's your press that arguably needs more work. You have a fair amount of pressing, but not as much as you are pulling and squatting.
Just a thought. Obviously, it depends on your particular body responses. If only two of six days for heavy pressing emphasis works best for you to bring up your press, then there you go. Done deal.
Just saying, you're already a good deadlifter, but does this routine do enough to bring up your relatively "weaker" lifts, is what I'm wondering.
Seriously, I'm obviously not an expert at anything. And no disrepect meant at all, just thinking out loud about a very interesting routine that I intend to try some day, and wondering if my thoughts are helpful for you.
Crush it! Looking forward to where this takes you.
