Backswing looks better if you want to swing. It looks to me like your natural move is more of a hitter, and that if you want to hit, your pivot needs a touch of crossline hip motion.
Part of the reason you tend to steepen on the downswing is that the right hip isn't cleared (flexibility plays a role).
In your hitting motion, think right hip over right heel back, right hip over left toes through.
hit or swing, you've got a solid move. The other area I would look is your finish swivel (in both cases). Hit some punch shots and finish with the club below your hands, check your alignments - where is the toe of the club pointing?
1. Natural move is more of a hitter? Can you explain why you say that, I am very interested.
2. I don't know what crossline hip motion means, but I will hit the search function.
3. When you say right hip has not cleared, is this more having the hip open, a la a Vijay Singh or are you meaning getting that weight more moving left after the "top" is reached like Hogan?
