Honestly? I don't worry much about bad sheds, unless they are a consistent issue with said snake.
One bad shed usually corrects itself on the next shed. I don't mess with eyes either - usually they come off just fine on the next shed.
With my recent move last month, I've had horrible sheds with most of my crew. It also seems to be drier here than it was in my old apartment, because I'm refilling water far more frequently.
