Sorry but for me, there is no comparison between i20/i25/i200 irons to the i210....
Not sure if it's just the elastomer addition or what but Yuge difference in feel.....I think they've gotten it right concerning launch spin combination. Add in the feel and you've got yourself a winner in my book!
I think they are good irons, just nothing that wowed and nothing that made them significantly different for me based on my short time hitting them. Performance may in fact be way better now, but looks and feel were extremely similar for me to their last lines. That’s also not a bad thing IMO because I’ve liked their past lines a lot. My take away from them was basically “yep, those are Pings”
