Improve your vibora by reducing power to 60-70% and adding side spin or slice (hitting between 3-4 o'clock on the ball) to keep it low after hitting the glass, making it difficult for opponents to defend.
This explanation from the coach is incredibly insightful if you're looking to make your vibora shot a point winner. It challenges the common idea that power is everything for this shot. Focusing on controlling your speed and adding the right spin, as the coach suggests, will make the ball much harder for your opponents to defend after it hits the glass. It's a smarter way to play this challenging shot consistently.
