Thinking its time for a new set of irons as the MP60 are very tatty and have rusty faces, impressed with the Nunchuk in driver, Virge suggested Modus3 most similar iron shaft. Got hold of a KZG EC-II forged cavity back shafted with a Modus 3 Tour X flex, Same length, lie angle and sw as the MP60 PX. Both clubs are aligned with the NBP at 9 Oclock. Reading on GolfWRX that they play a bit soft to flex but that they hit low flat bombs. Perfect day for testing flight and spin with a cold 25mph head wind. Hit a load of balls, including 15 with each club with a vertical sharpie line drawn on the ball where i hit it, alternating 5 with each club to ensure no grooved swing effect. Result is that the PX6 are staying. Very consistent shots generally just on the front of the target green, nice flight, held up by the breeze but definitely no ballooning. Modus 3 were all over the place. Back of the green, 10 yards short and wider both sides than the PX. Best 5 shots of the test were with the modus three in the middle of the target green. Other 10 with Modus 3 were the worst of the test and a mixture of what you would expect from the impact pattern.
