Current results point in the direction of what Bob recommended.

I tried something knew today. In the backswing I just gave myself enough momentum and smoothness to complete my shoulder turn. How did I know it was complete? Well, I have calcium deposits in my lead shoulder and heard a light crack 0,5 seconds before my shoulder turn was complete.

After that I just released my swing. Looked much more on plane and I finally made straight shots with my 3 wood. That was without thinkg about release.

Quite logical really, if you don`t complete your shoulder turn it gets that much difficult to get that shoulder on the inside and give the proper plane.

Also turning to fast made me shift, lose my spine angle and overswing. A slower turn until the "crack" seemed to smothen out my swing.

Still have to work on the finish position though (like ringer said) but I finished and turned through more naturally now. I will try it again tomorrow and let you guys know how its working out :D

No shift= Easier to finish. I think its that simple (unless you shift back ofcourse)
