Everything man-made is based on, or an improvement on, work or ideas that have gone before. That's how human progress is made. From what I've seen turned here and on other sites, all you plug builders are making very much improved versions of classic plugs. And some are better than others. I don't see it as theft of intellectual property at all , just an evolution of fishing tools. A different opinion and nothing to get my a$$ in an uproar over.
