New AP irons from Titleist - AP1 and AP2 sets - are coming in November under the 712 Series monicker. The Titleist 712 Series irons are due to hit retail on Nov. 18, 2011, with the AP1 set's MSRP at $112 per club with steel shafts and $135 per club with graphite shafts; and the AP2 set's MSRP at $154/$175 (steel/graphite) per club with Scotty Cameron Studio Select Newport Putter.
Titleist's first AP irons debuted in 2007, and the latest iteration includes a "712" stamp on the hosel, as visible in the image above. The "AP" stands for "advanced performance" and represents the effort of Titleist designers to engineer irons that combine both workability and forgiveness without deviating too far from the look of traditional irons.
To that end, the 712 AP1 and AP2 irons both incorporate high-density tungsten internal weighting to help boost MOI but without changing the center-of-gravity location (keeping CG the same distance from the shaft axis) or blade length.
Both sets, Titleist says, have been "significantly upgraded" for additional forgiveness and higher ball speeds. The 712 Series AP1 irons are aimed at the "aspiring to skilled golfer" and offer more forgiveness relative to the AP2 and scotty cameron coronado putter; the 712 AP2 irons are targeted at highly skilled golfers and are forged.
