I completely disagree with this flat wrist theory.Having a flat wrist at the top is an unnatural wrist hinging.Cup is natural..Why so many great ball strikers Had a cupped wrist?

Stand at address remove lower hand and hinge your wrist,What happens?It cups,which is the natural way for your wrist joints to operate.

Now, hinge it with a flat wrist--In order to get a flat wrist,you have to hinge with club going rearward..Totally not natural..
