You can also get braided leader and poly leaders to which you attach a short tippet of nylon.
They are NOT designed for changing a tippet in falling light with fish rising all around.
I finish the leader with a loop tied with a surgeon's knot to which I tie the tippet.
Floating Lines Strong Tapered Leaders. I fished a 8lb tippet for the first 2 days and then stepped down to a 6lb.
