Tsubame and Cray Fish lures were made to imitate live bait as closely as possible. Tsubame is made of modern, transparent material. There is a hologram inside which reflects light and makes it look like real tiny fish. The paint is just the icing on the cake - it’s light and subtle, which makes the lure more realistic.
The Cray Fish moves very differently to other soft lures, which makes it very appealing to predators. Even catfish and carp sometimes can’t resist these crayfish.
Crayfish lures work great with a microjig. If you want to have more control over the lure’s movement you can use a cheburashka with the Cray Fish. Carolina and Texas rigs are a great way to boost their efficiency.
