Are you worried because of how it looks on video?
Or are you actually getting under the sweetspot (with a too open clubface) and THUS coming over your downswing and flipping it.....?
Are you hitting compressed draws or even hooks? This is normal when people get on the NSA Train. (i.e. with a pure-Twistaway clubface control)
...
Here is an old swing video of mine (cover your children's eyes!!
):
http://media.putfile.com/Dome-Swing
As you can see, I used to setup really upright with really bent knees.......
I then made a REALLY inside backswing (product of my setup and also a flat shoulder turn).........
And because I Single Shift naturally (come over my backswing and down the Turned Shoulder Plane like Craig Parry) it looked really really awful.
Now- slicers come over their backswings a lot too......but the difference is that I do it naturally and have always done it and still do it. I don't do it because I'm trying to close a too-open clubface.
In that clip above...........despite the downswing coming hugely over my way too inside backswing........
.......I was actually fighting a HOOK and swinging too far to the RIGHT.
You can see this pretty clearly if you look at the path of the club..........and just the fact that my right shoulder is going DOWNplane indicates I'm trying to tilt and fight off a hook rather than close a too open clubface. A typical slicer comes over it too but their shoulder would go out towards the ball with not much DOWN. From a face-on view, I would have lots of axis tilt and a low left shoulder.........a slicer- not much tilt at all and a very high right shoulder.
Anyhoo- I needed to bend over more and badly needed some Never Hook Again there. Needed a steeper backswing with a "trace a plane line out to left field" downswing.
I did bend over more and did take a dose of NHA. (steeper shoulder turn, more outside backswing, swing more LEFT) I started hitting a huge fade and could not draw it at all.
I have since moved back towards NSA again (flatter shoulder turn, more inside backswing, swing more right) and right now I'm mixing the two depending on the shot.
I've only just started doing the "NSA side of The Matrix" stuff again but I'm hitting it great. I still have my weirdly Arched left wrist at the top BTW. (it does it now even when I try to open the face...it's a little "extra" move after the early swivel in the takeaway)
