Deadlift Bar Lowering

Currently I think there are two thoughts with multiple rep deadlift lowering

School 1 says explode off the heels as hard as fast as you can, then let the weight fall at the top portion of the lift, and immediately get back to the butt down position to explode again.

School 2 says to slowly ease the weight down, then come back up once the body and weight are in position.

School 1 will probably allow you to get more reps, while school 2 will probably tire you out, but activate more muscles.

Which is the better way?

Lowering is the eccentric portion of the lift.

If you’re doing conventional deadlifts, all you need to worry about in lowering the bar is the safety of the floor, the equipment, and yourself. There’s no need for an emphasized concentric portion that lasts as long as the eccentric. I can’t understand why you’d be doing more than 6 reps with conventional deadlifts.
