I am trying to wrap my mind around this. I built 4 thick bodied cranks, large bass cranks with fairly flat sides and weighted them as well as I could being these were my first of this type and I think they hunt right out the gate. They track straight forward but there is a different rhythm in the retrieve. It's like they are trying to find center but keep dancing left and right a bit but are still coming in with a nice wobble with out tracking off of center. I was pleased that they didn't spin in circles, even when ripped, but it wasn't what I was expecting but now I am going to keep these under guard since it seems I stumbled blindly on to the secret weapon. Don't ask for specifics because I don't know myself how I did it.
