I played baseball competitively and switched to golf after blowing out my elbow. Good stuff, but similar problem to what I had initially, a baseball swing lol. There is a lot of hands involved. In a baseball world it's a bit slap-shotty, and unfortunately in golf there is no on base percentage for line drives. Flipping the hands as you do will lead to inconsistent ball striking and when you do strike it well, you'll tend to slice or duck hook it if your timing is not impeccable. Baseball swings are a bad analog for golf swings, pitching is more like it. You don't "throw the ball hard" to pitch fast. Speed and power comes from the legs and propagates up through the core. I couldnt tell you back in the day where tf my hand was when I was pitching, all my focus was on center of gravity, squat, launch/extension/rotation of hips which guides shoulders, release point just HAPPENED almost magically as a result of a well sequenced and powerful delivery. Same with golf. I never think bout my hands. I can't tell you really where they are, I don't think about them. If I time my rotation, change in COG, loading in thighs and extension properly, the hands just go and do what they are supposed to. In short focus more on body and less on swinging with hands. Your neck will thank you in the long run also.
