If we are clear on the essentials and have a procedure for dealing with the "small stuff" and neither of us has an attitude of "my way or the highway", we´ll be able to have a safe and fun dive...and that´s why I get wet...
That sounds very reasonable to me. Some things affect the people you are diving with, and others don't. Personally, I don't care what you do as long it doesn't affect me. Backup reg placement affects me. Whether you have ankle weights on doesn't. I don't know enough about cave diving to comment on placing cookies, but I would guess navigation decisions would be pretty high priority. I don't know, I'm not there yet. At the level of dives I typically do, I'll dive with just about anyone.
