I have poor muscle memory and have no idea what I'm doing out there most of the time. My brother-in-law is big student of the swing, and he's always trying something different. He suggested I watch 1atomicgolf and I was watching some of his stuff before his DaVinci Code (which was Channel Lock's predecessor). JH is a hoot, as he often claims that " I can't hit it any better than that," but you usually can't see where the ball lands, so you have to take him at his word. I have tried Channel Lock, and since you play the ball back in your stance and come way inside, it might be easy to groove a swing, as you can't do too much else and still hit the ball. But I found I got about 1/3 pushes way too far right, 1/2 pretty good, and the rest were poor contact hitting too down too much along with the more than occasional duck hook. I found it much more effective with shorter clubs than longer -- to me, it wasn't at all helpful with driver.
I've tried a little of Count Yogi, who was a character and a half and taught a lot of stars back in Hollywood's golden age, and he preached playing the ball forward and swinging up the line. But as one of my swings often looks nothing like the preceding one or the next one, I get similar levels of success no matter what I try. Alas.
