Pros: Feel, workability, shaft selection, ease of fitting
While I admit that these clubs look great in the bag and at address, what won me over was their performance. Afterall, what good is a great-looking club that doesn't perform?
I had spent weeks on the web doing research on iron sets and went to Golf Galaxy with the intention of purchasing the latest Titlest AP2's. The AP2's felt good and looked good. However, when I started to hit various 6 irons over and over and considering the data I was getting, I quickly realized that the 58's were the club for me.
Mizuno's fitting system is available in almost any big-box golf store, especially with their shaft analyzer and the opportunity to hit any of their irons with a dozen different shafts. I was looking for a combination of shaft and head that would produce high backspin and would not brutally punish me for off-center hits. And, though the "pro" at Golf Galaxy left a great deal to be desired, I was there for the equipment.
When we put the True Temper GS95 shafts on the 58's, the club came to life. Even better, having never been one to work the ball predictably with my game improvement irons, I found that I could hit these irons straight or opt for a draw or fade with very little effort! The experience of calling the shot and watching it respond was intoxicating. And, all of this with an iron that wasn't yet fitted to my length and swing plane! Also, for all of you who dream of backing the ball up, the backspin on these clubs was impressive to say the least.
Since the store was experiencing an unusually long delay in their shipping, I left their on a mission - to get these irons quickly. The best part of that day was finding a set on Ebay that was only used for 5 rounds - with the GS95 shafts, 2 degrees upright, and at an excellent price. Apparently, he was measured for the clubs, but didn't have the opportunity to hit them.
Obvious Rule: Never buy clubs without hitting them!
A few days later I regripped the clubs with Winn Lite grips and added a 1/2 inch to the length which increased the swing weight wonderfully.
My set includes 4-PW. My first practice session at the range was very satisfying. Though I had only hit the 6 iron to that point, I was able to breath a sigh of relief as I worked my way through the set. Though the club gives you some pretty strong feedback on mishits, the direction and distance wasn't overly harsh. I discovered that there was no need to fear the 4 iron and that a wellstruck ball is richly rewarded. Shots that were only slightly off center were not affected much at all, though they didn't give me the smooth "buttery feel" of one hit dead on. I am not sure if I will put the PW in play, but I will determine that once the ice is gone from Michigan.
If you are considering new irons, I would strongly encourage you to hit the 58's - try several shafts - consider the data and don't be surprised if you find yourself dreaming about these irons later that evening.
Oh, one final thought. Before purchasing these 58's, I hit the Ping blades, Titlest AP2's, Callaway Forged Blades, and a few others. The only club that I didn't get to hit wasn't yet available in the states - the Ping Forged Anser Irons. Enjoy.
