Just like clockwork, Titleist is starting the process of seeding prototype versions of their 2018 iron lineup starting at the 2017 Quicken Loans National.
The big news from here at TPC Potomac is the unveiling of the 718 AP3 irons, which fit somewhere in between the AP1 iron, which is more of a game-improvement iron, and the AP2, which is more of a players iron. The AP3 irons have been described as somewhat forgiving and somewhat loaded with technology but maintaining the AP2 look (or close to it) that better players tend to like, with cleaner lines and a little less width and depth to top line, sole, etc.
The entire existing iron line, including AP1, AP2, CB, T-MB and MB are getting a refresh for 2018.
The general impression is that the company somewhat scaled back the aggressive use of tungsten in the 2016 lines, including in the T-MB, where the tungsten now is geared toward heel and toe areas instead of the entire sole. The cavities in the 718 AP1 and 718 AP2 have been somewhat redesigned.
The company isn't offering many more details on the new irons at this point, waiting until later in the year once they reach final versions of the products. Seeding is also going on in Europe at the French Open, then will continue on global tours in the coming weeks.
