You are probably used to less shoulder turn with hitting. IMO, swinging it is more critical to get a fuller turn and 'wait for it' before startdown. Try drilling with the exaggerated feel that your left shoulder gets behind the ball and 'hit the ball with the back of the left shoulder' - this will help you synch up the feel of trusting your hands and chest to turn through together. Also, full roll means FULL roll - until you can hook the heck out of it on command with big sweeping hooks - then back off until you feel a 'smoooooooth' steady rotation through - let that club feel heavy.

Also, it is likely that you are not using a startup swivel, which to you will feel like a 'big' roll of the clubface to toe up position - trust that. If you shank, you are too inside and need more 'up'. Ironically, that startup swivel makes the downswing swivel fairly 'automatic' and you won't have to focus on the 'full roll' - CF will take care of that for you.
