I've been successfully experimenting with the above photo'd idea for a bit now with Red's FLY and it looks pretty slick in water &action. I was schooled in this concept during the 70s from a prominent panfisherman, named Dave Goforth from Greensboro, NC, who gained national attention from a Homer Circle article in Sports Afield for his never fail "meatgetter " lure.Dave's panfish lure was a very special ,easy functioning little spinner and weedless fly combo that took him years to perfect; but ,after a while, he switched almost completely to small calf tail jigs which were even deadlier he found(with his meat concept,of attaching a 1" sliver of freshly cut panfish flank). Then he got into,with his continuing perfectionism, what he called a "pendulum lure", roughly like what is pictured above, which proved better than both of his other preferred lures! He "ran out of time" in getting this into exactly what he was searching for,however. I recently found it took Red's buoyant wool body& awesome fly combo to get it working just right, plus "Giant Bass" author, Bill Murphy's idea to gently,slowing DRAG a light lure across bottom ruble(rather than hop it) to get maximum attention from bass, especially. Also was thinkin this can get me over the pesky thin layer of bottom moss that some local lakes possess, which often fouls my boolies! Anyway, the weight & lever arm swing down as in a pendulum, especially after contacting a log or rock and kick that motion into the fly, which then will "shiver" (especially Red's fly) for a few seconds while resting.The ball weight on the wire arm seems to slide around rocks & stuff, so should tends to be more snagfree than a solid jighead. This is my light tackle solution to the pro bass guy's "new" expensive "rage", the so-called "jika rig"!!
Redear,I tie to the top (big end ,where fly is) of the snap, and had the ball arm rigs handmade by another great, late fisherman friend, who was also tinkering with this idea-he soldered them together. I make mine from paper clips and put em into a jig mold to pour the balls on (you can also use an old , soft-hooked jighead with the point removed and bent to form the loop!).Some of my initial experiments with this bottom dragging, light jig tactic was used previously on Ohio's productive Berlin reservoir, in checking clean underwater bars for bluegill & crappie in late spring -only problem was, we couldn't keep walleyes from devouring our tiny jigs!!
