I finally tied my first successful Shorbe Loop today. I've been fighting with arthritis in my neck that affects the thumb, index finger & middle finger of both hands. Needless to say, there are a lot of things my hands used to do that they can't do anymore. The loop I tied today will work, but it looks pretty sloppy. Long story short, I'm going back to using a single overhand knot for the big end of my leader, and using a double overhand to tie tippet to leader. It works fine that way, and I've never had a problem with them.
