Lately I've been going on autopilot and sticking to programs from the Archives, rather than designing my own routines. So far this year, I've gone through:
Waterbury's ABBH 1 and 2:
Henriques' 8-week Basic Strength Plan:
Cosgrove's Complexes for Fat Loss:
And just started Waterbury's SOB Training:
Overall, the save on brainpower from not having to figure out (and constantly tweak) my own routine is a huge benefit. I do believe it's something that any lifter should consider, regardless of experience. It's also convinced me that I'm almost-definitely going to "outsource" my nutrition as well, and will probably be looking into working with a diet coach.
