Camilo can get his swing speed up to the high 1-teens and JB is in the low 120s...when you swing that fast, no matter what you use, you are going to hit the ball rather high due to ball speed and spin no matter the tee height.
Also, a higher t'eed ball will help produce more of a draw while a lower t'eed ball will help produce more of a fade - I've watched Vijay tee it high and low depending on how he was trying to shape his tee shot
