Here is an iron set from the popular brand XXIO. If you are looking for one, please take a look. XXIO Iron Set 5th Generation Number of clubs: 5 (6-9, PW) Shaft: MP500 Flex: S The 5th generation XXIO irons are highly regarded for being "forgiving of mishits and achieving high trajectories and long distances with ease." In particular, the dumbbell-shaped tungsten weights placed in the sole contribute to a low center of gravity, resulting in high launch, low spin, and a wide rebound area. The MP500 shaft, which has increased rigidity in the grip area, also helps to increase head speed. There are many user reviews such as "golf became easier" and "it will be a weapon as I get older," making it a legendary club that balances ease of use and distance performance. Ease of use and forgiveness: The largest moment of inertia in XXIO history makes it forgiving of mishits and easy to get the ball airborne.
