I have several old Lucky Craft pointers (both 100 & 128 models) that used to be favorites. However, when I fish them now they rarely return to a nose down position after the cast and sit tail down at almost 45*. Could it be that the magnet has gone bad (or weak) that holds the weighted ball bearing in place? If so how do I correct this problem. I hate to retire old favorite baits if I don't have to. Dan
