I have been playing these clubs for just over a year now, so it is now a good time to write a review.
I built these last summer with TT DG Sensicore X-Flex PURED shafts and Golf Pride New Decade grips. These irons have been awesome. This is the first set of irons I have played with PURED shafts. I will NEVER not play them again - I am a believer in the PUREing concept. I hit these straighter and with better distance control than anything I have hit in my 27 years of playing.
I have also been surprised at how easy they are to hit and how forgiving they are. They don't play like blades from that standpoint. Yet, the workability and feel that you would expect are there. Twice I have tied my lowest 18 hole score and twice I have had 4 birdies in a 9 hole stretch (firsts also).
If you are looking for a "player's" club, this is the one. I can't say enough!!
