The Ultra-Light tuning kit for Henry's Vision, Circus, and Beach diabolos is an accessory that is designed to reduce the overall weight of these diabolos by 33g while maintaining their classic aluminium hub shape. The kit is intended to be used by younger players or those who are working with multiple diabolos, as a lighter weight diabolo may be easier to manipulate and perform tricks with. It is important to note, however, that reducing the weight of the diabolo may also affect its balance and stability. It may be a good idea to try out the Ultra-Light tuning kit and see how it feels before making a decision on whether it is a good choice for you.
