Blue dot, graphite shaft, stiff flex with Winn grips.
Most forgiving clubs ever used. You can tell when you have not made good contact with the ball, although, the end result is still very acceptable. With my prior set (knock-offs) I had only broken 90 once. Since playing with fitted i3 clubs I have score 83, 89, 85, 93 & 89.
Nothing, but I have gained significantly more distance (10-15 yrds/club) with these irons and I have not been able to clearly identify my range with each club yet.
The purchase of these FITTED clubs has been the closest move I have ever made to purchasing a swing.
