Guys, guys,
I am at a loss understamding how eye dominance can make any difference at all in the golf swing (snooker and pool, yes, because you are sightinhg down a straight cue)...after all, even if you are right eye dominant and your head goes to the right, whereby your nose bridge will block the right eye view to the ball, your left eye can still see it, clearly, in focus.....
So in reality you are not losing sight of the ball's position at the top, so what on earth difference does it make.....your head tends to come back to "two-eyed" on the downswing anyway....
Don't get bogged down with negatives, FCS!.....
