I have the 18* CPR, had it about 18 months. Fitted with a Graffoloy Blue stiff shaft which is spined and aligned. I use this lovely club off the tee as often as i can and as my go to club for second shots on long par 5's when i'm in the fairway.
I originally bought the club to replace my 2 iron and gain more consistency, i'm not sure if i could play a round of golf anywhere without it.
Highly recommended.
