went from i230 to i530 last year as I needed more forgiveness.
was so excited when the G440's launched.
picked up a set and reshafted with same shafts I have in my i530's and just couldn't get along with them. something about the wide sole and turf interaction just didn't work well for my swing. Don't have this issue with i530's.
IMO, I just think i530's are that good, very forgiving.
