Both Yamamoto's new hollow tubes and the solid Ikas are great baits, but I fish them differently. That is why I call the Ika a tube bait alternative rather than a real tube bait. They are different baits to me. The tail-splitting is sometimes a problem with other manufacturer's tentacles, which may not be so neatly split at times. They quiver nervously even when standing still.
Yamamoto tubes come in about ten colors, and they are all good.
The Garland tube simply will not get torn apart by cover or by fish as easily as most other tubes. These are the world famous original Gitzit tubes that were invented by Bobby Garland over twenty years ago. His brother, Garry Garland came up with the idea to solve how to machine split the tails. Garry is still fishing strong. He offers a complete product line of tubes at his Canyon Plastics web site.
