Some good heavy back movements...
I feel Deads should be kept under 5 reps and really explosive. I can't do higher reps with good form and without some unusual discomfort - but what's a dead for anyway? To peel a massive amount of weight off the floor! One exception is Stiff Leg Deads for lowerback and Hamstrings - those I will do and suggest higher reps in most cases (8-12). But for the sumo-style deads - stay heavy, and wear a belt.
Pull ups are a supperior back movement - never do them behind your neck...
T-Bar rows can usually be done with a wide or narrow grip and off back support with the pad... so its easy to go really heavy without much worry for the lower back...
For beating the isol lateral defecit - one arms dumbell rows can put a heavy load on each side... your knee up on the bench helps support your back...
Kind of like the T-Bar Row... the Hammer Strength rows off a pivoted free weight for a safe way to tackle a heavy load. There are a few variations but the only two I suggest are the one pictured below - and the one where you face toward the machine. Remember to never pull behind your neck with any of these... also, there is another good one that is kind of like an upright t-bar row...
