Perfect point of contact with ball – sugary place? (5,4)
I believe the answer is:
sweet spot
(Other definitions for sweet spot that I've seen before include "Area on club, racket or bat that makes best contact with the ball" , "providing an optimum combination of qualities" , "Best place to make contact" , "Best point of racket or bat when hitting the ball" , "Most effective section of racket" .)
