Love my TS1's, so I'm sure these are still forgiving and feel/perform great ... BUT, I would really like to see what their testing showed for yardage gaps, and at what swing speed, considering there are 9 irons covering just 28° of loft. And "Yes", I do realize that's only 1.5° less than the TS1's - but that was my only very minor gripe with them, and now it has shrunken even further. That said, I'm still kind of afraid to try them. I'm so happy with the TS1's I don't need any thoughts about switching floating around in my noggin.
