I took it back a bit and gained another 20lbs doing the 4-day TM until my first failure to increase weekly, after which I tried 531/TM mix similar to what I suggested in my previous comment, gaining yet another 20lbs. So, hard to say. I definitely do not think my experience is any kind of evidence, and a weakling that I am, definitely doesn't say much, but: The volume in 531 seemed, to me, more manageable.
(Recently after a reset I am back to more vanilla 4 day TM program with higher reps on volume. Simply due to getting bored.)
