That really blows man! I'm no instructor, but I understand your position: convictions vs job. It seems there's nothing to do woth your boss, when people are that stuborn (or stupid, don't remember how to spell ;)), you can't argue, even intelligently, because they wouldn't understand or they know they're not right.
I don't know about the Tanker, but go with the 3 straps and high angles for now. If your boss complains, ask if you have to dress like them, act like them, and so on. Just a suggestion...
