I have been using a combo of mostly white-ish plugs between Tomic and the WCFT Mother of Pearl glow plug with the rattle. I have caught fish on all of them but the one that has outfished them all by a wide margin is a 30 year old 602 5" tubby with the pins pulled. No Glow, no UV, no nothing except teeth marks. I catch fish on that thing at 240 feet where it SHOULD be invisible but yet it catches fish. So it must be the vibration or whatever other special sauce it has.
