Why the love for the tours over the others? I’m curious
And why go smaller in long irons and larger in GW?
When I first started looking at new clubs last September, after doing some research, I WANTED the MP-18 MMC irons. Seemed like a great advancement to what I had owned/played in the past. Hit them and the 2 other MP-18s and didn't care for them. The golf shop had just received the new 919 that day. Heads still had plastic on them. I tried all 3 919 irons. Didn't care for the Forged...just didn't resonate with me. LOVED the tours...looks, feel, performance! Liked the Hot Metal explosiveness and distance. So, when the HM Pros were introduced...seemed like a great combination of the Tours and Hot Metals! I just got lucky enough to win a set of HM Pros at the Sweep. But, to answer your question Molten, it mostly comes down to feel. I have never owned a cast club before and it's a big difference in feel. I'm considering going to a softer ball with these irons.
JB, Mizuno doesn't make a set matching 919 Tour GW. They do make one in Forged and Hot Metals. That's the only reason.
