I purchased a set of Sub 70 699 Pro irons. I had them paired with the I-95 Steel fiber X-flex shaft.
60 trial period
The face offers incredible forgiveness
Clean look at address
Great feel at impact
Less offset than other irons that fall into the same category.
As a high ball hitter, I very much appreciated the penetrating ball flight.
Workability wasn't what I would hope for from a club with the label Pro. The sole design promoted a straight or right to left ball flight. The sole design makes the club very difficult to hit cut shots.
Over-all I am highly impressed with the 699 Pro. I think any company willing to offers a trial period on their equipment knows they have a winner. The 699 Pro will check almost every box. Give Sub 70 a look. You will like what you see.
