This shaft continues to impress me every round out. I've really found my groove with it going to the light weight, x-stiff flex. It's getting me the perfect penetrating ball flight. It's not too low and gets me lots of roll out on these hard So Cal fairways. The feel is so good to me. I never feel "flexing or moving around" in my transition or swing. It doesn't feel too stiff or boardy either. It just feels smooth but powerful. I couldn't be happier with the results I've seen from it paired with the Darkspeed X. And did I mention it looks fantastic!
