Has anyone ever tried this product from Northstar Canoe or any DIY foam pad for one-shoulder carries?

I'm too lazy to install and remove the Swift screw-in portage yoke for my 29 lb. Keewaydin 15, which has a wide centralized seat, so I usually end up carrying it back and forth to my car with the seat on the base of my arthritic neck and shoulders. I'm thinking this foam block pad may be safer as long as it doesn't slip off or slide along the gunwale or my shoulder.
