Some form of stiff leg deadlift gets my vote too, just remember to start light & get the form sorted before you push them too hard & I'd also stetch a bit before doing them.
For back safety I'd do them from the ground, not while standing in a bench (as is commonly recommended) & don't go down so far you overstretch your muscles, mid-shin or just below knee is fine. About the height of a 45 pound (20K) disc on the bar is a good guide for those with an average build, raise it a little if you are taller or inflexible, use smaller plates is you are smaller or have excellent flexibility (that is just my personal opinion, others may have other views

).
I always recommend that you lift the bar originally like a conventional deadlift, then start the first rep from the upright position, as most injuries I've heard of from this move seem to have come from lifting from the ground for the first rep or rushing reps during the set. Neither of which are a good idea on this move.
