If you have a history of low back or hip problems, I'd just drop the bar if I had the right equipment. Especially once you lower the bar to knee level. I've had my best luck with resetting between reps so that has something to do with the way I feel.
If you start to feel like you're missing out on some of the muscle building that touch and go reps can give you, you could try out some rdl's and other posterior chain work.
I can't really speak from too much personal experience because I've never had the proper equipment to do that. I get enough looks if I just drop it from knee level haha. But I do know that at work if I carefully put down every thing I pick up versus controlled drops, I get a lot more soreness and have to do more work to take care of my hips and low back.
Really, just give it a go and see how it works out. Maybe you'll like it, maybe you won't.
