R-SARDINE
The R-SARDINE (Real Sardine) is the most favorite bait of various fish eaters.
The stable and long casting is promised due to asymmetry (in aspect of right and left) body with rear weight balance. In falling, it looks like a weakened bait.
Hooking opportunity in falling is incrased by the ring eye set vertically to the body, which enables the hook to move more freely. It also helps to make its silhouette smaller.
