I have a real good lag & release in my practice swing. So I know I can do it. But when it comes time to hit a ball, it's a different story. I just googled up this article. It makes a lot of sense:
I contend I can do all the drills in the world, but there is a chasm between the drills or practice swings, and hitting the ball.
I mentioned this on another forum and got the suggestion to just hit wiffle balls for a while, not worrying about the ball flight etc. I am going to do that, to try to add mental pieces to my practice swing until it becomes my real swing. And maybe it is as simple as repetition, which is basically what the article says.
I had already realized that for whatever reason I make a better release on a teed ball, be it the driver (my favorite club), or an iron. When I read the article and started thinking about how to make the move from practice swing to hitting a ball, I thought of the Hank Haney drill shown on the Barkley and Romano lessons. They had a hundred balls teed up, and the student just whacked them without thinking too much about the swing and results. Wiffle balls will just sit on top of the grass, as if they are teed up yet with no setup work. And I'll be less likely to care about the ball flight, and they're easy to retrieve.
That's my plan.
