I hit a friends new set of Ping i25 irons this past weekend. If you haven't hit these clubs, I suggest you check them out. If you are looking to buy new clubs this year, I suggest you check them out. Yes, I am endorsing these clubs. If I hadn't purchased new irons last year, I would certainly consider these to go in my bag.
I only hit one iron, that's all it took. I was hitting my Mizuno MP64 9 iron pretty flush down range. I grabbed my buddies i25 9 iron and flew it easily 10 yards past where my pile of range balls were. WOW. I proceeded to hit shot after shot to the same spot - 10 yards past my club. I then grabbed my club and hit it to the same, shorter spot where my previous shots were going. Yes, the Ping irons are longer.
The look and feel of the club is what you would expect from Ping. I owned a set of Eye2's back in the day and gamed those clubs for nearly 10 years. The i25's bring back fond memories. The set up is nice - not too offset. The topline is definitely thicker than my Mizuno's, but not like a super GI club. The ball flight was higher. The ball picked up quick and then sailed forever. My Mizuno hits a lower trajectory shot. The feel at impact is sweet. Not grain flow forged sweet, but you know you hit the center by the sweet sensation shooting up the shaft into your hands. The sound at impact was, for me, more clank and clack versus my forged iron, but YMMV. I checked out the rest of the set. The longer irons were progressively larger and thus more forgiving. Personally, that was the main drawback for me. I prefer a more aggressive look. I'm not ready to trade in my Mizuno's just yet, but the performance of the i25's is noteworthy. In all, these clubs looked and felt great.
Trying to get at the root of the distance gain, I checked out his personal setup and the loft comparison's of our 9irons. First, the Ping is 1* stronger. Next, he had his irons fitted 1/2 inch longer than standard. He used the Regular flex shaft, but tipped them. Would that plus the 1* equal 10 yards? Finally, there is Ping's technology. They claim to have made the face of these clubs "more lively". I guess they did! If distance is your thing, you should certainly check out these new irons. Enjoy.
