Go lighter than you think the first time - I find eccentric hamstring movements give you DOMs like nothing else.
I SLDL pretty much every week as my hamstring accessory exercise, often on Tuesdays after squats (noting I deadlift the day before!)
Worth noting the rep range too - my DL rep range is 5 for working sets, for SLDLs I use anywhere from 8-12 (normally 10-12). Have to do it slowly or I find it become a lower back exercise and I use it to target hammies.
Yeah, I do 3x2-5 reps for my main working sets of deadlifts. I'll do 3x8-12 SLDLs to complete "leg" volume for that session. Then it'll probably be something like 5x5 OHP, 3x8-12 T-bar rows and 50 lying leg raises.
