Certainly a very impressive looking Driver and Irons.
That being said, one thing my old man always told me that seems to resonate every time I think about trading up is, 'Would the best player in the world hit your clubs better than you?' Of course they would, better working on your game unless you're at the top of it.

Great looking clubs!! I don't know if its just me but the C16 iron profile looks very similar to the T-MB utility irons. Would love to see a comparison of the two together.

I have the C16 driver and have a number of different shafts that I've been trying. FYI I own a Trackman and an E6 simulator. I like the driver. The current setup I have is a Diamana X flex, blue board, setting at C4. I like the flight, distance and spin is below 3,000. I have played 3 rounds the last week, 76, 78 and a 79. The course I play, Hidden Valley CC, in Reno, NV is the qualifying course for the Barracuda Championship. I'm 59 years old and play from the blue tees. I also have the irons, KBS Tour X, lie is 1.5 flat. I love the irons. I can work them both ways, high or low. And the Vokey SM6 wedges are fantastic too! I've altered the swingweights on the driver and irons. Driver is around D1 and the irons are D1. I am not using the Titleist grips. Hope this helps.
