Can you have your hands too far forward at impact? What are the possible pitfalls of being in such a position?

Geometrically I'd say yes you can have them too far forward. According to one of the 1L principles, no part of the lever assembly should move forward independently. Usually, this is the club head moving forward independently which equals throwaway, but I would think it also possible that the arms could move forward independently giving an arched left wrist. This would also violate the principle, and disrupt the flying wedges, although the consequences would be less severe than with clubhead throwaway.

Pitfalls: An arched left wrist produces push shot tendencies according to the book. Lowpoint moves forward. The left wrist becomes the fulcrum of the lever, shortening swing radius (or at least that's what I've heard!). I'm sure all these could probably be compensated for however, if you knew what you were doing.
