Has anyone used these? Picked up several packs at walmart in the green pumpkin color and they have been killing it for me. Have them rigged on a keitech arky jig 1/4 oz. and have also tried them on the bitsy jig. They have worked awesome on both

Great little tube with a light insert head. They imitate a small crawdad really well. 

Great bait to fish on a drop shot,and I also fish them on a jika rig or a split shot rig with a EWG size 1 or a 1/0.

I used to catch smallmouth on these.  No weight, but it was situational at the time.
