100% accuracy? I do not care about yardage issue here. I only need idea on marker movement on long irons.
Then you are on the wrong path . Alex if you want to get better , you are going to have to practice . You are going to have to take the time , and learn your clubs . If the wind is left to right , you play left of the ding line . Right to left wind , play right of the ding line .
You also have to consider spin on the ball , as well . Top sin , back spin , or no spin , all will affect ball flight , as well as distance . If you want 100% accuracy , then practice 100% , and you will learn what to do . Go put your time in , and stop trying to find an easy way out .Good luck with your game .
