His question was not "how do I learn about golf".
Even so, I dont see how listening to former major championship winners is "the worst way to learn about golf".
In my 2 week experience in the forum, listening to forum members may quite possible be "the worst way to learn about golf". Suppossed pros advising a grip change to fix major swing flaws is significantly more "horrible" than anything Johnny Miller has EVER said on TV.
Whilst Millers advice is inaccurate in reality, we know that feel and real are not the same, so i would go with you on this one blue72ss. The feeling of opening up the face through impact can certainly produce fade, even if the reality is that the clubface is closing down but it hits the ball in a more open state. Whatever gets the ball to do what you want it to, I'd rather have a feeling that works than a full understanding but an inability to do it.
However, define a swing flaw for me. Sure there are certain things that are not optimum in golf, but sometimes two wrongs CAN make a right if they compliment each other. every pro has compensations and things that are not textbook........but sometimes they are the things that actually make it work
