Good job....the key thing is to make sure and stay with the newer, better swing, even when you have the inevitable bumps along the road. So many people work on things and implement them for a round or two, but then go back to their old habits once they play a bad nine or 18 holes. I'm guilty of it myself...finding something that I know is right, yet I'll get off to a bad start and revert to my old ways because I figure I can scrape it around with bogeys and an occasional par rather than sticking with what will help my game and lead to easier pars and birdies once I get it down better.
