I really have no beef what-so-ever with doing your safety stop horizontally. This is partly due to the fact, that this is the attitude that my gear puts me in naturally, and partly due to wanting to not have huge ups and downs. As for fastek buckles, you won't find them on my BP and wings either.The myth of the horizontal off gassing study MAY have been made up by someone who, being well intended, did not understand the true reason behind maintaining a horizontal position.
My real beef is with made up reasons for doing something. Some people just HAVE to justify the way they dive, even to the point of inventing LAME logic to do so. No one knows everything (not even me! :tease: ) (Yes, you can quote me on that) (but stop grinning) Sometimes you are given lame information by people you trust (check out the NitrOx thread on the mechanics of breathing) and I for one accept that as inevitable. Just because I expose the illogic in an argument, does NOT necessarily mean I fully disagree with a particular person... just the way they got to their conclusion. BTW, the crusades were probably "well intentioned".
But... why get sidetracked on the "minutia" as MHK calls it when there has never been a documented injury or death attributed to a failed fastek buckle? It is my ever so humble opinion that injuries are very rarely caused by a diver's gear. Inattention, stupidity, inadequate training and taking chances probably cause more injuries and deaths than ALL of the other causes combined by a factor of ten.
But if you are going to join an army, then you had better get into proper uniform. Its a given that you may not understand it fully, but you still need to do it. The drill sargeants have a ton of reasons for it. Some of these reasons are worthy while some are fallacious. It really doesn't matter as long as you put on the uniform the way they want it worn. Why put yourself at a disadvantage from the start? You risk alienating your instructor or at the very least distracting him from how you are doing your skills. Humble yourself and learn from your teacher. It's all good.
