At the Pinehurst TTI last year, they had some on hand. I think it was the -4. Comparing to my T300, the feeling was awesome. But the distance was similar. I couldn’t justify 2500-3000 for 5 or 6 irons as a result. I checked the Titleist.com site to confirm which one I trialed, but Cncpt doesn’t show under irons or using search. NLA?
