Depends on whether you use a flasher / dodger or other attractor before the lure. I'm using little dakota-blade and bead attractors about 18-24" ahead of the lure. I run 8 or 10-lb. test to the attractor and the same off as a leader between the attractor and lure. Lighter line can get twisted to hell (even with swivels) and/or snapped off if a big fish hits and pulls. If you don't use an attractor you could probably get away with 6 lb. I don't go lighter than 6 lb. for fishing depths...

I use 10 pound superbraid with a small swivel then up to 100ft of berkley vanish leader , and let out all the leader up to the swivel and attach the leader 2feet from the swivel on to my blacks releases. works great for me . "reel it in "
