I don't even pretend to know enough to comment on the specific dives. But my favorite instructor gave me great advice on my first ever class, and I've followed it ever since. He said something like:
"I'm human. I make mistakes. I will do my best to not lead you astray. But if you ever hear me tell you to do something that you know is wrong, call me on it. You are in charge of you on every dive. I'm here to guide you and give you the knowledge you need to dive safely, but to stay alive is your job and to be safe you need to make the right choices for yourself."
