All of their scents are pretty much enzyme based....they get real technical about it. I tried some Marukyu Isome worms. They catch fish but I can't stand fooling with the liquid that they are packed in. They also have a huge assortment of fish attractants....or as we would call it...chum. I bought 2 bags of the stuff and used it in a couple of private lakes. It was also made by Marukyu. it was about 5 years back...but I tell you that stuff attracted fish. It was some sort of fish meal with the enzymes added. The Japanese use that stuff pretty heavy in saltwater.
