Well written, Jim, but who is this Ken DeVries dude?
Allow me to add a thought. If you ever get a monster fish on and you're running core down the chute or behind inline planer boards, you may want to pull it. On more than one occasion I've seen fish run straight over to leadcore and use it to remove the lure from their mouth. Apparently they see it as a useful tool for that purpose, and it does work. Three years ago I had a monster on while fishing off Muskegon and neglected to have the full core pulled, even though we had plenty of time to do so. Yep, that fish boogalooed straight to the core and released itself, and when we pulled the core the lure was firmly embedded in the dacron sheath. A hard lesson was learned that day by me.
