I think trying to keep your head in one still spot in space can be worse then any head dropping if it's not right for you. Check out Hogan, Trevino, Moe Norman, Johnny Miller, Byron Nelson, Arnold Palmer... all with pronounced head drops in their swings. The list goes on and on and on. Johnny Miller always talked smack about Tigers head drop, and he did it as much as anyone. Compression is good if you know what to do with it.
