The crawler version of the Gulp pulled behind a spinner was just hammering the fish.........guys were double hooking the heads of the "worms" as to not allow them to get thrown when the fish started to thrash plus, by double hooking the heads it gave a little more spin to the crawler which enticed strikes.

My partner has been using this stuff for a while and he swears by it....especially the artificial leeches, when fresh ones are tough to come by while he is on the road.
