I'm a Hotspot fan and drag either a Coyote or Coho Killer behind it on 5-6 feet of 25 lb. leader, specifically Trilene Big Game. Why? My mainline is 50 lb. Power Pro, 12 pound diameter so it knifes through the water with no slack to the downrigger release, and lets loose with the slightest touch. But man, the stuff is like steel cable, and if you get a hot fish that slams it going the other way or jumps on your leader you are snapped off like right now. So I use the long "rubber band" leader material. With this setup I get the hook in most fish that bite and land a good percentage. The long leader doesn't seem to affect action, and basically the whole thing works for me
