I don't grip my bow tightly. I let the grip fit into my hand as I draw, and then just tighten my grip enough/close my fingers around it to keep the bow from springing out of my hand when I shoot. Doesn't really matter whether I have leather on the grip or not.
I don't particularly like high wrist grips, but don't have any trouble changing from one to another, or from leather to no leather, checkered, etc. All that being said, I prefer smooth leather to rough side out/suede for my bows that have leather grips.
