My lab did the North Slide many years ago. I don't recall any issues with it, she always did fine on slabs, better than on loose rock (like the South). I actually got a cool picture of her bracing herself on the slide, her back was level and her legs were at the slide angle. I didn't leash her on slides, and found that she would always find a way around what to do.
That being said, we did have to lower her down some ladders on the CannonBalls (can't recall the trail). That was, umm, interesting.......
