Path and Flat Left Wrist

[mdelgado]

I've been working with Ted on improving my path through the swing to eliminate a nasty shank. We have had a lot of improvement by changing my shoulder turn to eliminate Roundhousing and, thereby, preventing an over-the-top movement.
Yet I'm still struggling with an over-the-top path primarily due to my inability to hold a flat left wrist impact. I think what's occurring is that my left wrist bends (or is it arches) forward and throws the clubhead outside of the path.
Any tips on keeping my wrist flat through impact? I've discovered that trying to keep the wrist flat while releasing is like trying to pat your head and rub your stomach at the same time.
Great forum--thanks in advance.
