My head speed is 44km/h. I was using these clubs until a year ago, but I'm selling them because I switched to S flex shafts. The club heads have a wide sweet spot and the shafts are carbon, making them easy to handle. I think these clubs are suitable for players with a head speed of around 38km/h to 45km/h.

There are some scratches on the soles, so please refrain from bidding if you are concerned about this. There are no issues with use. The golf bag is not included due to aging.
