I wasn't aware of the plastics that take on glugs.... now I want some but thinking about it that ali hamidi or whatever his name is always glugs his plastic bait.
I used plastic a lot last year and I tried glugging and not glugging and tbh honest I don't think it made any difference at all. Remember plastic is non porous so it cant absorb anything it just sits on the surface which is washed off as soon as the bait hits the lake bed
