While I'm not a crappie / trout Magnet fan,I do use jigs tipped with more active plastics,mealworms,and other live baits under a float depending on what species I'm fishing for.I use the slip float technique most often,letting the wind move the float which activates the jig .If the water is calm,I give the rod tip a few twitches while reeling in the slack.After several cast covering an area,I may adjust the depth ,hoping to locate fish.
