I have not seen the bars if you will on the above fish posted by spark. I don't have that on any of my fish. Other than that I think they are dang close to the same? Not sure if those bars mean anything or not? Like I said no expert here on pure or not pure?? What I can say is I do agree with you on the fish trucks some here can be iffy sometimes, and you better know what your getting. That's why I don't normally use them.
