Yeah, I don't put too much faith in indoor ball testing, and they helped prove that for me last year. And there were minor differences in the data. The way they phrased it and characterized some of it though really gave me pause, and I'm surprised they aren't being more aware of that stuff, especially with their recent quotes being plastered all over Mizuno's website and stuff. Just seemed like some really poorly chosen words in that moment.they did mention that the biggest difference they felt would be noticed is from irons and wedges. The woods (Driver and fairway) were virtually identical and hard to tell apart.
I think dry ball data is tough, but outdoors will tell the better picture.
