Throwing my 2c in for what it’s worth… which is less than 2c in many instances.
If you want to continue to do a traditional deadlift, there are different schools of thought on doing touch and go or doing singles. You can find some very strong lifters in favor of each. One of the best arguments I’ve heard for singles, especially for beginners that want to learn competitive lifts, is that it allows them to focus on their setup every single time. I typically do singles from the floor on anything over 80%- I’m not saying that’s the right way or the only way, but it’s the way that I do it.
If you do continue to do traditional barbell deadlifts and want to opt for doing singles instead of touch n go, I would suggest the following- you need to control the rest between each single. Between each single is a cadence or ritual. It needs to be short and repeatable almost exactly and you need to step back up ready to pop.
My 2c. As far as not needing to deadlift, I don’t think anyone needs to deadlift outside of competitive athletes or those aspiring to be, but I think it gets a bad rap. They can be done safely and effectively and are a great training stimulus. That being said, I know there are a lot of people who advocate for the trap bar. Either way… it’s not a hill I’m willing to die on. The question really is whether you want to deadlift or not.
