I am thinking about making a top water hard bodied frog out of balsa wood. My plan is to cut a rough profile on the band saw, shape and sand, and then cut a slot and add a 3/0 or 4/0 worm hook on the back. I am trying to get a walking action out of this bait. Should I add more weight to the back of the frog or a small amount to the front to balance it out a little bit?
