Yesterday I took my launch monitor to the indoor driving range to see if I could reach 170 with a hard 7 iron, well I was getting 163 to 165 so I figured that's about right but I saw a couple of newer range balls and used them, I hit 167 and 169, O.K. now I'm wondering what if I use good balls that I would use on the course so I grab a pro V1x (scuffed) and a pinnacle extreme out of my bag and swung aggressively with the 7 iron and got 177 and 179 of carry. Now I'm wondering if getting my yardage from these stupid range balls is the cause of me blowing the ball over the greens when I really hit them flush???? Now what???
