Conclusion: The new Ping G15 promises to give the avid but game improving golfer, a highlight reel for 2010'. The iron has all the markings of a game improvement iron that is ready for prime time.
Pros: The biggest positive is also one that is ground-breaking - the wider sole puts this iron on auto-pilot. The G15 also has stronger lofts over its predecessor (G10) which adds distance but not at the expense of control and spin.
Cons: The wider sole does definitely gives it a look of a game improvement iron. But if you can get past this minor detail, you'll find it extremely forgiving, playable and most likely become your best friend.
