I'm currently doing different combinations of sets/reps for them. Squats are 5x4 for heavy day, 3x8 on light day, and 3x8 for goblet squats. Deadlifts I am running an anello cycle, wanted to see how that would work, and they far outclass any of my other big lifts. Bench is 5x4 as well. Everything is is 5x5.
That being said, rep range is sort of up to you. I like low reps, but higher reps are probably just fine for most people.
