I do not feel a need for it personally! Especially on metal lip swimmers. If there is a density issue with the top of the plug having a slight desire to roll when you folks "Hydro Orient" the weight of a belly weight, grommet, swivel and hooks will offset this effect.....after all it is a swimmer and it is designed to roll and/or wiggle. I had this discussion with an engineer and he agreed. As Paul says to each his own!
