I was on the hunt for a new set of Irons so went to the pro shop to try a few. Never gave Titleist a though until I tried them against some of the other clubs I was keen on. The Titleist had me won over!
The 712 AP1's are an improvement from the 710's. Improved feel, forgiveness, looks (thin top line, more "traditional" looks, etc.). The long irons are easier to hit, which could help improve your game, which would lower your handicap. On the flip side, the Titleist AP2 710 Irons cheap are still a great set of clubs. They're still forgiving, have a great feel, looks, etc.
The Titleist AP1 712 irons price have a slightly different sound at impact then the 710 model. Because I have to say that sound was one of the things that made me really like these irons! It seems with premium irons (in the same class) there is so little difference between them you have to start nit picking them to find the ones you really like.
They are both really nice to hit. I liked the pro model better but after hitting a few of centre I thought the non pro was the go for me. The sales bloke there then gave me the Titleist AP1 amongst a few others to try. Well thats when the new contender come along. I liked the Mizuno brand, I liked the look of them I was drawn in by all the great feedback they have been getting etc, but the AP1 sounded and felt just that little bit better for me. The computer showed I was hitting them better.
The 712 is supposed to have a more durable sole and it's supposed to launch a little higher on the longer irons. Truth be told, I couldn't feel the difference. Visually, I do like the cheap AP1 712 irons more because it's a little bit more refined on the topline, but that's personal opinion. Titleist admit that they did not want to change a lot because the Titleist 710 AP1 was so successful.
Generally, both the 710 and 712 will be clubs that launch a little higher in comparison to AP2, CB and MB, but they still give you the ability to shape your shots. That's why I love these Cheap golf clubs so much - they can be used effectively by both single and double digit handicaps! If you want to pay a little more for the newer stuff, go right ahead! But both of them will perform well. I am an advocate of buying some of the older stuff to save some money. For instance, I rather buy a top-end 2011 club for the same price as a middle-tier 2012 club.
