I was a lil' bit worried trying to chose between the Sim2 Max irons, the more affordable M4 irons, or the newer, and significantly more expensive Stealth irons. However, after playing a few rounds, I'm glad to report that I'm happy with my choice. The Sim2 Max irons added 20 to 30 yards of carry and they feel smooth as butter when hit just right, while still offering some feedback on thins and fats. Great clubs for a very reasonable price. As for Muziker, what can I say, they delivered right on time and in great condition. Thank you very much.
