Yes my spine becomes more vertical and my shaft is more upright at impact and my hands are much higher. I have a tough time hitting the ball first. I used to try to practice the drill where you imagine your hands are under a shelf at address and come back under the shelf at impact. Good thing I was using some foam rubber. I usually feel like I have to lift my left shoulder up to my ear to make room for the club shaft at impact.
You gotta work on this . . . . I battled/battle the same thing. You do that move and you can hit the freakin' ball anywhere.
The reason I told you to get that 1/4 inch thick piece of plexey glass is so you can MAKE yourself hit the ball first. You can set it 6 inches back of the ball whatever at first. If you dump #2 early you'll crash the glass. . . won't screw your club up but it'll make you hit the ball first and keep your alignments.
Do you have a video camera? You need to really monitor your pivot. If you can get a microphone stand and a dowel and a pool noodle you can set that deal up so it rests on your head. You gotta figure out how to pivot with your head staying on the wall and your booty sliding on the wall behind you.
You can have the best wedge/power package alignments in the world but that goat hump is gonna disrupt everything . . . gets your plane line shifted and increases the rate your clubface closes . . . .disrupts low point as well.
FEELS . . .
left shoulder down much longer as you come thru . .
feel like your ass goes way back and your chest comes way down during your transition
imagine or actually drill with a wall behind you . . . when you start down turn AND SLIDE your left butt check to the wall and forward of where it was at address.
You'll have to really exaggerate your practice swings . . . make sure you video to monitor it if you can . . . do a lot of slow motion drilling too. You fix this and you'll be amazed how much better your swing will plane and how much easier it will be to keep your wedges and hit the ball first. Go get 'em . . .
