I'm having trouble getting my hands in front of the ball at impact with my short and mid irons i'm nearly there but not quite, i'm sure this is the reason for my very high shots which are struck well leaving a white "scuff" mark from the ball in the middle of the club but very very high ball flight , 7 iron goes 150 but i'm sure if i could get the ball lower i'd be a fair bit further , by the way i had my swing speed measured with a 6 iron and it was 87/90 mph which is not to bad so i'm sure i should be hitting it longer . Any advice ?
