Bill have you looked into something like a slide diver with oversize ring and weight on it? Also another rig I enjoy is a 45 pound Cooper line that I spool up to 400 feet of cooper and run it behind planer boards or off the side of the boat up to 400 feet back? Another possibility for you would be to use a jettison tripper plastic holder with pin pull out to drop the lead ball on a strike. I have used 2 pound balls to drop.
