I totally agree with Can Putt... I was aligning everything except my shoulders which were about 5 inches closed. This throws everything off because the tendency is to square the club head at address but when you come down to the ball it will open again. Notice that when I moved my shoulder to the right alignment position the club head followed without purposely moving it. Only then everything is aligned - feet, hips, shoulders, and clubhead. Now the club head in the downswing follows a natural path to the ball, nice and square.
