Let me add to my previous comments, that probably one of the best ways to make sure you get what you want from your hunt, is for the individual hunter to work out his own code of ethics and hunting behaviour, and put it all in writing to his PH beforehand. - AND ask the PH to reply with his comments.
That way, the PH knows what kind of a hunt he needs to provide to the hunting client and the hunting client can have his hunt exactly the way he wants it.
