[Mud Ball]

Hi
I've been thinking about my left wrist and struggling with the right feeling at impact. I understand the left wrist is either level, cocked or uncocked.
I understand that the downswing and backswing positions may not be replicated i.e. cocked on backswing at one point and uncocked on downswing at not necessarily the same point.
At impact on a standard shot what position should the left wrist be in - level, cocked or uncocked?
Thanks in advance,

Mud Ball.
