"The Snipe Universal Butt Section Leader"

If you are using knotted leaders, tie the loop in the butt section. Various leaders are then tied to go loop to loop with this section. Use a Nail knot to attach the butt section to the line. Make the Butt section about 55% to 60% of the length of your longest dry fly leader.

If you are using a knotless tapered leader, attach the leader to the line with a nail not and forget the loop to loop connections, or like suggested above use a short piece of nylon nail knotted to the line with a loop on the bitter end.

It is always better IMHO to have the smallest, most inconspicuous knots in your leaders. Loop to loops therefore come off a poor substitute for a blood knot. I usually cut the loop from a knotless leader and use a blood knot to attach the leader to the stub attached to the line!

Try it I think that you'll like it.
