I bought the 1 iron golf irons last summer and dropped my handicap by 4 strokes. There is a large mental hurdle that you have to get over in order to play these clubs. It is next to impossible for the single-digit handicap types to overcome the paradigm shift, because they are usually better than most of the people they play with so why should they change. I don't blame them for being "non-believers".
I also don't play very often, 3 times a month is great and I am lucky to hit a driving range once per week. I don't play enough to get really good, especially my horrid putting.
Here is what I find in a round of golf...by the time I make the turn, I am hitting the sweetspot on my irons consistently and that includes the high-lofted clubs. Why? Because even if I havent swung the 8i all day, when I get to the #10 tee box and pull the 8i, I am confident because I have been swinging virtually the same club all day leading up to that shot.
I like them and play better with them. I have been know on several occasions to tee off with the 3i on 350yd holes rather than put my drive in the trees. Then I can hit a 6i or 7 into the green. Many naysayers talk about the distances being compressed. I don't know for sure, like I said, I don't play very often. I am buying a GPS this Spring and will record my yardage per club throughout the Summer.
