found a way to avoid pickerel biting off my crappie jigs
Up until last weekend I was losing a dozen jigs to picks per trip fishing a local mixed species lake. I had some thin leader wire (.011) laying around and decided to rig a 2.5" leader on my 1/16 and 1/32 oz jigheads. I figured that since Beetle Spins work on crappie, why not a smaller wire leader. The thin wire didn't deter the bite of even the smallest fish of any species and many decent size crappie, perch, sunfish, bass and pickerel hit aggressively! You might think that a rigid wire attached to the line tie woudl hamper lure action - it didn't, at least not for the horizontal-travel presentation or vertical finesse action at the boat.
A few years ago I attached a thin wire leader to a small split ring and it did not work as well as the wire fixed at a 45 degree angle to the jighead hook shank. The split ring allowed too much lure wag and that is one action a grub should never have IMO.
