I was sold on the i500's based on hitting the i700 when I was getting fit for my Ping g400 hybrids until I saw Tony's pictures and the review of the "distance players irons." I LOVE my Mizuno experience with both the MP-59s that I upgraded to 850 Forged when I decided I needed a touch more forgiveness in my long irons. I'm not happy with my fit on the 850's (they convinced me to go with 1/2" long as opposed to the 1" long I've been playing for nearly 20 years) so instead of reshafting, I'm looking at a new set.
These are stunning and if they maintain the buttery feel I'm used to, I'm all over them next spring!
