While you are somewhat limited on your lift selection for loading (and even then you get 3 different rotations), your selection for pump and MRs is nearly endless. For example on a tier 2 day, you could hit your back with 7 different back variations (8 actual sets). If you wanted to focus on thickness, you could make both pump sets thickness, and make 2 of your MRs thickness, and 2 of your loading lifts thickness.
