The best placements for bandeja/vibora are often the center (5th wall) or to the opponents' feet, varying speed and slice depending on opponent position and aiming to create pressure and get a subsequent volley. Avoid the 4th wall placement.
This lesson from coach Sven offers a deep dive into where to play your overhead shots, specifically the bandeja and vibora. He uses real match analysis to show why certain placements work and others fail. Understanding the difference between playing to the center or to the side, and adjusting speed based on your position and the opponent's, is crucial. It's quite useful if you want to improve your overhead strategy beyond just hitting the ball over the net.
