Selecting the proper leader starts with deciding what size fly ( ) you are going
to be fishing with. That's where to begin to determine what leader to use.
To use this chart, it's an easy
3-step process:
1st: first decide what size
fly you intend to use; (the fly hooks shown here represent the normal range of
those used by fly fishers in most freshwater fishing situations in the US & Canada);
2nd: then click on the hook image in the chart below for the size of the fly you intend to use; (the
hooks are standard dry-fly type hooks the size of which are depicted quite accurately.)
3rd: the details on what leader to use to match up with
your fly will be displayed.
