Top Yo - Undulation

Large and responsive bimetal model.

This is the signature model of Top Yo team member Xin YuHong.

With a diameter of 57mm and a width of 46mm, this bimetal model gives the impression of being relatively large for a full-size model. However, it is enhanced in many ways to enhance its overall performance.

The large gouged shape reduces sleep loss to the utmost limit, which is combined with the stability and rotational power of the bimetal design. The slight step in the profile (perhaps the namesake) also makes the model highly suited for rejections, and gives it a powerful presence.

The overall thin body allows the yo-yo to move with light force, and its responsiveness is also appealing.
