Stacking with a dummy flasher

[Tailwalker]

Do you clip the dummy right to the downrigger ball, and about 3-4ft of thick mono?

How far up the cable do you run the lure/bait? Do you go just high enough up the cable to exceed the the length of the line on the dummy? And how many pulls is typical before clipping on?

Go to the thread on "Power Mooching", look up #7 for the diagram.
