Yes I have a set of the first irons and a demo of the newer irons but not the newest (YET). I will be getting a set of the NEW irons that will be selling after the show. The irons allowed me to drop 1 club, so instead of hitting an 7 iron for 150, I hit an 8 iron. Not to mention that if you dont hit it clean, it is more forgiving.
The main reason I bought so many shares, is that I and many others, love the irons.
I have the old driver and it hits straighter than my R5, I think with a better shaft or the new shaft I can also match the distance.
