A bottom attack model was born in the popular "Usakura".
The best feature is the asymmetrical folded ear lip! It lures trout with its shimmering rolling action and traces it in depths of 1-2m. 

When you fall to the bottom and land on the bottom, the lip touches the ground and you stand up in a handstand posture. Since you can appeal the presence at the bottom, it is very effective to catch it with a retrieve that keeps the bottom such as stop & go.

After landing, stand on your hands!

The left one is "Bottom USakura" and the right one is "USakura S".

We also pay attention to the size and angle of the ears.
