I don't know your swing or your handicap, but you have three options. You can go straight forgiving cavity back, slightly harder to hit cavity back, or a more difficult club like the Mizuno MP 30's. Here is what I suggest. If you are only going to work on your game a little bit, like hit the range only a few times a month, go with the Mizuno MX 23's. They'll give you enough forgiveness to keep the game fun.
However, if you are willing to practice, I highly recommend the clubs TaylorMadeFan suggested. That is, Titleist 690 CB, Nike Forged Pro Combo, Mizuno MP 30, and the Ben Hogan Apex FXT Forged Combo. These are all very well made clubs, and very accurate. They are also lacking in the forgiveness department. At first you might have trouble. But, if you are willing to take some lessons, and dilligently practice those lessons, your scores will drop with these clubs. The reason for this is because these clubs will force you to groove a consistent, proper swing. They won't let you get away with a garbage swing like the RAC's will. No, go with something that will force you to get better.
If you have anymore specific questions pertaining to this subject or these club models, just let me know!
