The majority of recreational golfers, and even some better players, suffer from chronic slicing. Anyone who has experienced this problem knows how frustrating it can be and how difficult it can be to overcome. One of the main reasons so many golfers are unable to straighten out their banana ball is because they attempt to find a cure without properly understanding the disease.
To fix your slice once and for all, I suggest first understanding what fundamentals are key to solid ballstriking, and then taking measures to incorporate those moves into your swing. By so doing, your slice will disappear automatically.
