I use a barrel swivel where the braid meets the fluorocarbon leader and a snap on the other end to make switching & untanglings baits easier.

I use a black duo lock size 1 on jigs and crank baits.
I just purchased these to use for casting light jigs.
Used a similar make years ago and really liked them for not having to re-tie as often when changing jig heads.
