How many lifts did you rotate? I am think of trying something like this for the ME lifts:

Week 1 - 3rep max
Week 2 - 2rep max
Week 3 - 1rep max
Week 4 - rotate

I'm thinking of rotating 3 lifts for the ME days and for supplemental rotating every 6 weeks. Did you ever rotate in a deadlift variation for ME work?
