Good jig head to use a rotary vise on. Looks good. I used to troll for walleye when I lived in KS. About the only thing I ever used was a Hot-N-Tot crankbait. I have trolled them behind the boat on Oologah at times and only caught a couple of Crappie and Sandies. I would think the walleye population has grown fairly good in Oologah as I rarely see anyone specifically targeting them. The rig you have should be a great all around trolling bait. Drop a heavy sinker with it for the depth. Where did you find the mould?
