One of the most frequently talked about aesthetic qualities is the thickness of the topline. This year, you'll be looking down at a topline that is slightly thinner than that of the previous AP1. Blade length is also a bit shorter in the short irons. These two improvements combine to give the AP1 a much improved shape and feel that will likely appeal to many players as it did to me.
I'd like to note that at times the Titleist 710 AP2 Irons didn't feel as stable during the downswing, towards impact as what I normally like, but I attribute that to the shaft. It was by no means unplayable, in fact, it was quite the opposite, and I don't think it affected the performance of the irons in terms of distance, but it did leave a little bit to be desired at times. If anything, they were a little longer, and they certainly got the ball high in the air though this could be due to the lighter, softer shafts coupled with lofts a bit stronger than the irons I normally play. Still, the overall feel on a flush shot was superb.

Titleist plans to begin selling the irons later this fall, though again this marks the first week that they're rolling them out to their entire PGA Tour staff.
Titleist says that the new Titleist 710 AP2 Irons offer better feel, more forgiveness, and an improved shape with a thinner topline throughout the set and a shorter blade length in the short irons. The new feel is hotter. The first thing you'll notice in looking at the AP1 is that the back is now notched, with a bit more weight spread to the heel and toe. The tungsten weight no longer shows through the back. The red/black/silver scheme remains, but this is the first shot in which you'll notice the new "TPU arms." The TPU actually goes all the way around the perimeter of the club in the AP1.

Titleist is a classic company, always have been, and always will be. This being said, these look good enough to take on a date. The Titleist AP2 irons with famous golf clubs irons have an amazingly thin top line when looking down at address, which is what the majority of golfers are looking for. The AP2 irons look like a blade at address, and that goes from the 3 iron all the way through the PW. I would rate the looks of the Titleist AP2 iron at a 10/10.
