Hey fellow left handed player on the right side. Same as you.
First of all, do you find playing vibora to the right side of the court easier than left?
If so, you need to turn your body more to the left as you are waiting for the ball.
How much left? A lot.
Ask a friend to lob a ball towards you from the opposite court on the left side. You move to the position to play your vibora.
However, don't hit the ball. Just as you are about to hit the ball, stop.
Look at your feet. Where is your front foot pointing? It should point to where you want the ball to go.
Where is your chest facing? It should at least be facing the left fence or even slightly towards your back left hand corner.
This was my problem after looking at hours of game play.
I thought i was facing the left fence. My chest was facing the net square on. Hence my vibora to the right is an easier shot.
Not perfect yet but knowing the problem is half the issue solved. Still working on it every week.
Vamos!
