Nico, Im not certain we are talking about the same thing. All of my baits have the hole, only one has this odd empty space hollow spot in it. If this has been going on for at least two years, it is extremely odd that me and those I fish with have only seen this happening recently. I should send you the bait (its brand new), but only if you promise to send me a new one too only without the hollow spot :P

Hey Matt, pipe in here would ya
