I have made a lot of anglers "Damiki rig" jigs over the years and I was told about it long before most heard of it. The name comes from the bait used, the Damiki Armor Shad and the one thing critical with the bait is that it doesn't exceed 3". Now, it other parts of the country that may be different but you may want to talk to elite series pro Jamie Hartman, he couldn't get bit on a drop shot on Cherokee lake but he was able to catch them on the Damiki rig. You don't cast the rig or hop it along the bottom or swim it, it is a vertical jigging technique in which you simply drop the rig to where you see the fish on your graph and then let it sit there, little to no movement. It is cool/cold water technique that I was told is not used much, if at all, outside the winter months. Iabass8 is spot on when he mentions it has been around for years in the walleye anglers arsenal and I actually have a DVD from 2002 showing James Lindner fishing a fluke on a jig head in the same manner for smallmouth up in Ontario. It is very effective but nothing really special except that it has been dialed in on certain lakes in which a 3" fluke style bait is attached to 3/8oz to 1/2oz Erie, Aspirin, or Mnnow head jig with a size 1 or 1/0 light wire hook and then sat semi motionless in front of fish in a vertical manner. When the elite series guys were fishing Cherokee lake Randy Howell had custom Erie jigs made with a 3/0 Gamakatsu hook because he didn't like the small hooks on what was made locally and it was that critical that he not only missed the cut but he never got a bite on the rig while others around him in the same area were catching good fish with no issue. The reason is because the hook and bait size is very important in those lakes where it is a winter staple, I'm sure in other parts of the country a larger bait fished on a different head style will work but the lakes where this rig became famous is because it is refined down to a specific bait on specific jig heads fished a specific way and it is not cast, trolled, hopped along the bottom or swam, it is a vertical technique plain and simple.
