Ditka, The type of sling is your preference. Whatever feels comfortable to you. I use a Nylon 1.250" Military sling.I don't carry my rifle that much by the sling. Usually when I do it's cold and I have a jacket on for padding.The wider slings are allot more comfortable then the narrow ones. If you plan on carrying it allot and in warm weather get a wider one.About the Foam Rubber,I'm sure in time it will disintegrate.I feel safer using Nylon. It's durable ,strong and dries fast. I mainly use my sling to pull the rifle up & down while I'm getting in and out of my Climber.There are several makes and models to choose from. It's up to you to see which one fits your likes.I agree that you should get some Flip up scope covers.Check some of the shooter's supply catalogs.Ruger Redhawk
