Limp, try this: stick your arm out like you are going to shake someone's hand. make sure your wrist has no flex, no extension, no deviation. 100% neutral wrist. now put your racquet in your hand while keeping that same neutral position. The racquet is pointed up and at a slight angle right? It kind of 'looks' c0cked back if you look at it from a certain angle right? And it looks just like how the pros are holding their racquet in the take back and just before the beginning of the forward swing right? This is what they are doing. Neutral, loose wrist. Then they pull forward, the wrist flexes back and they make contact with the bent back wrist.
