Listen. If you have a welded loop on your line, what you want is a blind splice loop. Look it up. Most guys double catch it I just simply run it about 12" with a single splice and its bombproof. If you dont have a loop on your line, cut your end of the line on the angle and work it inside the backing for about 12", nail knot on the end (I use 50lb braid) and a flexible thin walled shink tubing or a drop of aquaseal. Best methods to connect your backing right there.
A lot you guys probably dont know this method but... imagine a braided loop concept, use your backing in same fashion for a perfect transition.
