I have a set of R9 TP irons that I still play and bought a set of 690.cbs a couple of years ago to tinker with. Consistency wise, the R9s are my go to. But the feel of the 690s when struck perfectly can’t be beat. I’m in the process now of doing some shaft rearranging. The DGs make the 690s very hard for me to get a decent launch angle. I may take one of my KBS Tours from the R9s and do some testing.
I also have a couple of various older wedges that I can stick in a bag to help fill it out. I’ve also been adding to my Titleist driver “collection”. I have a 983K, 905T, and a 909 D2. None of which I hit particularly well (shaft selection is key) but I love the look and feel when struck well.
I was also given a full set of Titleist Lite 100s, persimmon woods included by someone at my church. Haven’t swung them more than a couple of times but I have them in case I get the itch to play some throwback golf.
