I was watching iFish a few weeks ago and they were fishing for Australian Salmon in SA. They mentioned a way of attached the gang to the leader so that it would hold the pillie/mulie out and make it look like it was swimming...it wasn't just a regular knot around the eye of the top hook.

Can anyone shed any light on how this might have been attached and have any information on where I can get pictures or video so that I can repeat it?

Thanks heaps
