Yeah, that's why I'm doing 5x1 instead of 1x5. I've seen guys in my gym doing deadlifts for reps, but even for the guys who set up with good position on the first rep, they usually get out of place on subsequent reps because the bar has moved at an angle due to the non-circular plates.
I started DLing with those, and only recently got the chance to switch. Happiest day of my life.
