I tested the new Mizuno Pro S-4 irons from the launch monitor to the driving range and finally through 18 holes to see how their distance, spin, feel and forgiveness actually perform. Mizuno says the S-4 is its most forgiving S-series iron yet... but are they good enough to earn a permanent spot in my bag?
