Excerpt: Callaway has a reputation for bringing power and distance to the game, allowing golfers to hit the ball harder and higher. The low center of gravity and humongous sweet spot made the Big Bertha and many X Series models popular and pervasive, so wouldn’t you expect Callaway to do the same with the RAZR X Muscleback Irons? Perhaps, but the irons do not; instead they focus on control, consistency, and comfort.
Conclusion: The new Callaway RAZR X irons will do well and for good reason. They are a game-improvement iron that has earned a Gold rating in Golf Digest Hot List for 2011 irons. This is another GI iron that not only deliver quality but also performance. The low CG coupled with a high MOI will sit well for the average player looking for a boost.
Pros: This iron will definitely do well for the average player looking for more distance and playability. The lower CG will be a good fit for golfers looking to get their irons airborne quicker to get more distance.
Cons: This one seems to have that built up Callaway look that will not fair well with better players. But then again, it's not made for the lower handicapper, it's made for golfers looking for game-improvement (bordering on super game-improvement) iron. Also, I would have liked to see more of a shaft selection.
