Many years ago, while attending the Aeronautical program at Utah State University, we studied various materials for rag wings. At the time, I determined that a material that went by the name of Razor Back, was the finest material available. Fiberglass! I don't know if it's still avilable, but if it is, you should consider it. It is a glue on process (no envelopes) and tightens up using the same dope process as grade A. Once completed, you put a small sticker on the rudder, and from that point on you are never required to subject the surface to a punch test. It's a true lifetime fabric. Several years later, we recovered our PA-18 Colt with it. It was wonderful. A little more difficult to install, but well worth the effort. Check it out. It was 25 years ago that we used it, but at that time I was convenced that it was the best available.
