Hey John,
Have used one for years. I have a bad left knee. I would rather slide half way done the lane on my belly than to stick once. The teflon in this product will slide on anything. It has been a lifesaver for me. Now that being said you must be a release as you slide person ala Marshall Holman. Not a plant and crank type. But if you have problems with sticky approaches, this will cure that. Hope this is of some help.
