Had my first range session with it today. Overall, I can already see improvements.
It's very difficult to hit straight, off that bat, for sure. It starts left and hooks even further off line (RH).
That said, after just a few balls, most shots were hit solidly, just left. By the end of the session, I was hitting some straighter ones.
I was alternating between the DST and my 7, 8, and 9 irons.
Will come back with more!
