Lets try to learn something about leaders. This does not include tippets, just the length of the leader. If you really want to mess this up include furled, braided, twisted or whatever too. The main question is this. Does the length of the leader depend on the length of the rod or the weight of the line/rod? Should a leader for a 9 foot rod be longer than a leader for a 6 foot rod? How about an 18 foot leader on a 5 weight rod? Does the size of the fly matter? The smaller the fly = the longer the leader? Is there one real answer, or not?
