I have caught several 20-25 pound lakers and pulled them through a 10" hole. It takes patience. The hard part is gettting their head pointed up into the hole, which gets a lot harder when the ice is really thick vs. early ice. I have seen several big fish lost at the hole when the lure hangs up on the ice at the last minute. Once you get their head into the hole, you can grab them by the jaw and pull them through.....
