I have been out on the course 4 times with my new Blackstone Irons.. Initially, I was chunking my hits quite a few times trying to find the revised pattern swing required for the irons .....but by the fourth-round consistency came into play. I was hitting the balls down the middle of the Fairway on a consistent basis. A major Improvement in my game! The only issue I found, being a six-foot-three muscular character I found the irons to be slightly too light. Ideally, the mass of the heads should be a few Oz heavier. But on the positive side, I've seen a major Improvement in my golf and my golfing experience. Very pleased with the purchase.
