The poor man's down rigger (bottom bouncer to crank) works. Use to do that then switched to leadcore. Boards work, but the ones we typically use won't work with leadcore.
Yes, I/we will put one bb rig out with spinner n crawler, and have the other 3-5 rods cranks. I use a 3 oz bb and usually only in 9-12 fow. We will use boards, usually one if conditions are right.
