I tie a barrel swivel to the end of my tipup braid backing. Then at the leader i start with a snap swivel tied to the leader material (whether its superbraid, flouro, mono, etc.) I store different leaders wrapped around a piece of pipe insulation (the round foam). If I need to change leaders in a hurry, either on the ice or the night before I can quickly swap them out without having to retie new leaders for every trip. Keeps things very quick, easy, and neat.
