Very solid construction, top notch quality. Again, these clubs will be in my bag the next 10 years.
On the first course using the new clubs, I shot a personal best. Every hit I wanted the ball was nearly there every time. I did not feel any impact in my hands when hitting the ball. These are the best irons I've ever played with and will be in my bag the next 10+ years.
The grips. I will be changing them out sometime soon. But that is being nit-picky.
If you've been starting to play golf more often and are looking to upgrade from those beginner (wal-mart) clubs, get these clubs. You will definitely feel and see the difference the first time you take them out and get some course play. Not for the beginner, but you don't need to be pro to see the impact in your game.
