We went with the J Hook but thats because it was the same price and had a very pretty design. If that design was available in overlap, would have gone there. Ours was very easy to install without an wrinkles or folds but I guess we were lucky because I hear a lot of people have issues with anthing other than overlap. I think the Pool Gods were just allowing us some glimpse of Heaven since the start of the yard prep, digging and install was Hell.
