Not to jump on the bandwagon, but the Drop Kick for sure! I was so fond of that jig last year. Everything from the action, to the hook, to the colors... it rarely didn't get used in a day of targeting panfish!
Otherwise if I'm hitting walleyes at first ice, I'll probably be shallow and dropping down that new Leech Flutter spoon... if you haven't seen that one then you need to check it out!
