You're absolutely right. The hard work and experience shows.
The big things I noticed were your approach is much smoother, a little less height on the backswing, and you're now letting the ball do more of the work compared to just ripping the cover off all the time. It seems that you may be doing more with surfaces or layouts, and that's a good thing.
That IQ Tour Pearl looks like a great match for you too. You were locked in to say the least.
Good luck with JBT the rest of the year. Even though you're not that much younger than me (I've got 13 years on you at the most), you definitely have a very good future ahead if you keep working hard like you have.
