My father inlaw has Mizuno JPX E300 and King Cobra S9 iron sets which he has bought and wants to give it to me as present cause he has new clubs now. I can't make up my mind which set to take. I can't take both cause he wants to sell one.
My handicap is 18 and I haven't used any of them at all. I have tried them out in golf range and they both seemed very good! Both are very forgiving clubs. Can anyone please help me decide which is better?
