We use the offshore inline boards.Since there are only 2 releases on a board,what you call middle is what I call forward release.We use the orange OR 19 release in the front and the red OR16 with pin in the rear.Twist the line and put that in front release with loop facing forward.Making sure line is behind pin in rear release or the board will come off.When a fish hits hard or when we jerk the rod,the line comes out of that front release.Then board comes in easier and will not dive.
