I can't answer your question directly, but I think I understand your point.
When I train, I want to train without leaving anything out. My philosophy is: To be able to defend from a technique, you must know how to perform a technique.
With this I am constantly pestering my sensei for more techniques that are not necessarily in our curriculum.
I would say, were I to have the opportunity train in BJJ, that I would want the full gambit when I train. But I would also have to overcome my pride and tap when the lock is set to avoid injury.
So, in my uninformed opinion, bring the heel hooks.
