I would suggest the same grip AFTER you have aligned the club face. If you want to open the club face, set the clubface open and square to the target, the grip the club with your natural grip while it is in the square position. Same goes for delofting your club, close the face up, square it to the target, THEN grip the club. That way your club should be square to the target every time and you won't have to worry about the strength of your grip.
