I have a set of these. Mine are D4/D5 swingweight shafted with Roddio I-10 in 'SX' flex. I should have posted a review, but what I can tell you is that they are great at punch shots, (PW/9i especially) with a nice solid thump through the ball. Maybe these are a great 'diggers' iron. I bought them hoping that they would give me a nice soft feel from full shots but I'm not feeling that at the moment, but this is probably the flex of the shaft more than anything. Comparing to Yamaha 2011 Tours, these are slightly longer with a little bit more offset, a smidge thicker top line and sole. Lovely satin finish.
