I've been looking for something like a Zoom Mag II since I started pouring. This is my go to worm and from what I can see there is not any molds out there like it. It's a flat sider with a very thin tail and narrow body. I am pretty sure it is not patented because Zoom usually puts the patent or patent pending number on the label if it is. Anyone know where I can get an injection or hand pour mold similar to the Mag II? Like it has been stated, it has a different action, especially when sinking, than round worms. Yes, I do buy several of the colors, but many of the colors I use to use have been discontinued.
