Current Back Routine

Hey guys, just looking for advice to see if any improvements can be made to my back workout.

I train traps with my shoulders, and the gym doesn’t have dedicated pulley cable row machines. It dies have hammer strength but I prefer free weight. The only Exercise I’m not comfortable with is dead lifts due to an old lower back injury

Currently I’m doing

Narrow grip pull down - 1 warm up set, 1 working set to failure, 2 drop sets to failure

Wide grip pull-down - 1 warm up set, 1 working set to failure, 2 drop sets to failure

T bar row - 1 warm up set, 1 working set to failure, 1 rest pause set to failure, 2 drop sets to failure

Barbell row wide grip - 1 warm up set, 1 working set to failure, 1 rest pause set to failure, 2 drop sets to failure

1 arm Dumbell row - 1 working set to failure, 2 drop sets to failure

Dumbell Pullovers - 1 working set to failure, 2 drop sets to failure

Hypertension - 3 sets to failure

I feel I’m hitting all areas of the back, just wondering if anyone can think of anything to improve this workout outside of dead lifts? Possibly could switch the wide grip pull-down for chins. Thanks in advance
