Are these an attempt at fly fishing tactics through the ice? Would you add any type of bait to the jigs, like a minnow or spike? Seems feasable that a bead head immitation should work for pan fish. On the other hand pan fish eat anything you throw in the water as long as you find them in a pile. I have ice fished for quite a while, but i am trying to learn the in depth techniques that are involved in hard water vs open.
