On a related note, can you "overbend" the right wrist?

Overbent right wrist = arched left wrist

Do you mean: Is it ok to Arch the Left Wrist? Absolutely. Late Release, it will be Arched. The amount of Bend in the Right Wrist is determined by BAll Position, Amount of Right Elbow Bend and how far ahead of the ball your hands are at impact, given a stationary head. Not everyone who trys a late release will have an arched left wrist. If your rate of accelleration is great, then the clubhead will catch up before your hands get too far ahead. It's possible and desireable for those with a Late Release to have a Flat Left Wrist at Impact. That would always be my goal. If you Arch the Left Wrist you Deloft the Clubface.
