Fair enough - if you want to be party to a case of the blind leading the fully sighted, I'm game.......

Seriously though - I'm simply focusing on keeping my left arm straight and my chin high. My overswing comes from my left elbow and wrist getting too involved at the top of the back swing (and thus bending back a little, a lot, way too much...). I focus on not letting them get involved at all.

Once I keep things slow and relaxed and focus on not "putting the club back" and instead focus on bringing my shoulder around and keep the hands and arms inactive, just cock the wrists and keep things simple - this tends to stop the overswing.

It's all much earsier said than done. But I'm sticking with it and it is helping

How have you been battling it - would you have any better suggestions for a novice?
