Native Son - Here's for a description. To connect fly line to backing the best technique, at least from what I have heard, is to put a large loop in the backing. Large meaning large enought to put your whole real, or stored fly line through. To make this large loop out of dacron core, there is a way of splicing the loop with a 'chinese finger trap'. This is different than the single blind splice that you see with the braided mono loop connectors that you can put on the tip of your fly line to loop leader. Anyway, you form this large loop with a reverse blind splice and have another loop in the end of your fly line. This allows an easy change of fly line from backing, and is the most secure way of forming the loop. There must be an illustration of this on some web site, or in some book. I haven't found it. Trey Coombs or Deke Meyers' books don't have them, although both talk about other techniques of splicing. I'm sure this is what most fly shops use when they rig a reel with fly line. Hope this description might invite some responses. Mo
