Do you have any video? Do you have to burn it to get your swimming action? Just judging by your pictures, I bet that thing sinks like a rock only being 3 or 4 inches long with ballast in two sections and you took out probably 1/4 of the wood and replaced it with lexan. That may be what your looking for the bait to do not sure?
Vodkaman is right though put the first hook in the first section of the bait. Honestly putting the hook in the tail is not the best thing either. To me, you want the tail section to be the lightest and most free of all the segments.
Anyhow just my two cents
