Over the past month, my golf game and ball striking has been the best it has ever been. My scores have dropped consistently into the low 80s, but over the past few days, I've been realizing that my swing has become way too steep with my 4-6 irons. I have been taking very large, deep divots with my wedges through 7 iron, which are resulting in outstanding straight, high trajectory shots, but with my 6-4 irons, I'm hitting the ball towards the heel and above the sweet spot of the club. The ball marks have consistently been towards the top of my club face. Maybe three or so grooved from the top line. After hitting these long irons the best I ever had, I'm starting to wonder why I am getting too steep. There is almost no trajectory on my long irons now, and they're not quite going where I'm aiming. Any tips/ideas?
