Some things I think you could refine:
...limit it to one all out set each week. Warmup, ramp up, crush it and drive on.
Straight Arm Lat Pull Downs
...Do not like. If I were training you I would punt them.
One Arm Dumbbell Rows
...These tax the snot out of me. And they take time. The time factor can be a burden especially when you are lifting heavy. Consider 2 sets instead. (I like higher rep sets on these, but mileage may vary) Or you could use barbell rows instead.
I like the deadlift and dumbbell row combination (not trying to be argumentative with LTL). They are my favorite 2 back builders, and for a pure hypertrophy program I think they are better than doing deadlifts followed by barbell rows. The deadlift, barbell row combo can beat up my lower back. Mileage may vary...many times I do them together anyway just because it takes me 8 weeks to load the dumbbell rows and I am a lazy sot.
