I went back to the range today and it seems that the shanks are gone for the most part. Swinging with my feet touching to stay balanced and bringing the club straight back helped alot. I also slowed the backswing down a bit. Thanks guys.
The shanks may be out of my system, but something has replaced them.
Again, the long irons and wedges seem fine, but now 5-PW launch far higher than normal. I'm talking like if I hit 5 iron you'd think it was a 9. Carry distances seemed only about 5 yards shorter than normal. I moved the ball back a little in my stance, but that did nothing for the lauch angle, only caused a push. I normally hit really high but this was insane. Now I definately need to get a lesson...
