Spine tilt and FLW

So, from a FO view, I clearly have a bit of targetward head movement from top of the backswing to impact. I also see a clubshaft lining up with my left arm just before, rather than at or just after impact.

Is it plausible that by working on keeping my head from moving targetward on the downswing, I'll learn to hold the left arm/clubshaft angle longer as a fairly natural reaction to avoid burying the clubhead in the ground behind the ball?

Hmm. I would say I have the exact opposite problem. My head moves backwards away from the target and I release my angles because of it. I can find plenty of guys to move targetward and keep the wrist angles.

Usually if the head moves away from the target in the backswing you see the hands start to flip at the ball, because your left shoulder rises up and you see people loose spine tilt, so the hands loose there wrist angle to compensate.

But in both regards you want a stead head. Its ok to have the head move slightly in the backswing. Some good golfers get away with moving the head back a bit. But in the downswing the head will be very steady, maybe some downward head movement (tiger woods sit down move).

I could see moving your head forward would cause you to come in to steep, so you might compensate that way, by trying to shallow out the swing by flipping.

But, just work on keeping the head steady. You can do slow movements, really work on feeling the club through impact with the head staying still. Check out some of the 5 key's videos in the Swing thoughts thread, a lot of good tips and drills there.

My point with the picture was to show that even you go more forward than recommended you can hold the angles. I guess I should probably but a disclaimer on the picture saying only for demonstration.
