I will normally drop a snake from astern at about 1 kyds, followed by a circle runner after I pass overhead (listen for the MAD call and drop) if I am sure he is deep. If I think he is shallow I will lob one in from 5,000 feet up, wait for it to go active then go in low for a better shot. That way he is thinking about the torpedo that just started pining and looking for me in his scope.
