The original Scrounger heads collar is about half as tall and is thicker then knock off Wiggle head collar. Both have about the same action, a tight wiggle when the soft plastic trailer is added. The Scrounger head was made for salt water use and came with an eel like plastic tail trailer and had smaller hooks. The Wiggle head was made to meet a spike in demand back in the 90's, then faded when newer bigger trout type swim baits hit the western market. I have never stopped fishing this lure and it still works very well. Originally used the trout colored 6" sluggo's and that combo works best when trout are targeted. You can add any color sluggo, Fin-s, fluke or what ever that look like a minnow or bait fish. Because the hook rides upward and the head oscillates side to side about 45 degrees when swimming, the scrounger will go through cover very well and gives off a lot of viberations and color flashes like a bait fish. This is a reaction type lure and the bass will case it down from behind most of the time. A high percentage of strikes can happen close to the boat, so be alert for following bass and don't slow it down. I had better success speeding the retrieve up, then slowing down for some reason with this lure. You can't reel too fast if the bass really wants it and thats why a normal retrieve, then faster when you get a curious bump seems to work so well.
