I recently tried both the callaway apex and apex pro irons and found that the original apex were more consistent than the pro version. This was just my feel though, everyone has their own feel for clubs and what they like. If you like more of a players iron that has a smaller head then the pros might be for you but if you like the look of the bigger head and you find that that makes it easier to hit consistent shots on a bigger face then the original apex is a good option. Both iron are very nice clubs and a great option if you are looking for clubs but there are very slight differences between these clubs so if you are considering buying one or the other you should try both before buying.
