You should probably look more towards a true game improvement iron. Titleist doesn't make one, but most companies make an iron with a fat sole and a split cavity, with more weighting for higher ball flight and in turn they are more forgiving. Also, it's not always worth buying the 2011 (or most recent) set of irons, or driver or whatever. You could probably buy a good game improvement iron from 2008 or 2009 and the price reduced because of this. Some good examples of game improvement irons are the TaylorMade Burner irons, Ping G series, Nike VR Cavity or Nike Slingshot just to name a few. You can also go the route of buying a set of clubs geared towards a beginner. I've seen these from TigerShark, Founders Club and Jazz, just a few off the top of my head.
I currently have a set of AP1's but if I used them when I was starting out, I would have found them pretty hard to hit. Hope this helps.
