When I make my leaders I use 6ft of 20lb floro then to the end of this i tie in a small ring that the carp boy,s use. Then I have 12" of 20lb tyger wire and to finish i use Fastach Snap size 3. To attach to my fly line I use a simple loop to loop. This set up has never let me down and I don't have to keep shortening the leader every time my wire get hammered.
