I don't think there's any point in trying to lower your hips or add "leg drive" to your deadlift, it's a fool's errand. You should have *loaded* hips, *loaded* glutes, and loaded lats and erectors and abs ready to pick the weight up like a peanut, but thinking that you should be "driving" is going to make you think you should squat the weight, and you shouldn't.
If you can bend over at 90 degrees with a flat back and grab the bar then all you have to do is load your hamstrings and glutes by sticking them back, then you can pull. If you can't bend over at 90 degrees then you'll have to compensate by loading your hamstrings, glutes, and then use your knees to break forward and get you closer to the ground. But that's how you should set up the deadlift.
on a related note, I used hook-grip on 405 yesterday, fuck thumbs
