I quit using screw in steps after hearing a few horror stories, even though I have always worn a harness. But with a harness, I was afraid I'd literally rip myself a new orifice before I came to a stop.
And I wear light gloves regardless of the weather when climbing a ladder. I thought I was merely keeping my ring from making little clinking sounds on the way up.
Tell you what tree steps are good for, though. If you don't use a lifeline, like with a climber? If you have a tree step in your pack, and God forbid your top and bottom give away? You could screw in a tree step and take the pressure off your body to avoid suspension trauma.
