They differ in speed (Bandeja slower, Vibora faster), spin (Vibora uses sidespin), technique (Bandeja chest/shoulders push, Vibora wrist/elbow for power), and tactical purpose (Bandeja maintains net position, Vibora attacks).
Understanding the key differences between the Bandeja and the Vibora is super important as you move up the levels. Coach Ewan does a great job here explaining the subtle but crucial variations in technique and purpose for these two common overheads. Knowing when and how to use each shot effectively will really help you control the point and pressure your opponents. This distinction is a fundamental part of mastering overhead play.
