Have played every G iron made. Currently have played some of the best golf of my life in South Florida. G425 has given me the feel that the G series has been missing (albeit, I play in 80 degree weather). I had the G710s and loved them but for me the G425s feel waaaay better. Now, fast forward to the ZX5s, I have been flirting with them for weeks and will not sell my G425s but am certain I will add the ZX5s. They feel incredible with same distance and same trajectory (83mph irons speed). Try the ZX5s if you want amazing feel, for me I am playing in some nervy events the next few months and NOTHING gives confidence under pressure like ANY G iron...IMHO.
