Another thing. I usually put something inside the slide to keep it firmly on my finger. The new Rock Slide all I needed what a piece of Velcro (soft carpet like side) stuck the the inside of the slide. This can be tripled up to get it thicker. I have also used round felt floor protectors that are made to stick to the bottom of a chair leg. They are quite thick and also have adhesive. I like it to be tight enough to stay on my finger if I have the slide pointing down.
