I find this whole DIR, not DIR, whatever thing rather boorish. Before there was DIR or doing it any other way, there were a bunch of people that went out diving, went into caves, wrecks, deep, shallow, whatever, and we didn't need all of these nonesense "rules" to tell us what was safe: we just dove safely. I think the modern world is too laden with manuals and rules and lists, and it takes the fun out of everything. To me, DIR stands for Doing It Rigidly and, to me, that's no fun. Also, there's no 'superiority' or 'inferiority' involved whatsoever one way or the other: its just a few people's idea of what works better FOR THEM - like religion. There are many roads to the top of the same mountain, so, climb the mountain, have fun, and don't sweat the small stuff (like which side of my whaterverthehell I have a ring shaped like a D, but really more like two L's, that is more than 2 inches, but less than 3 inches long that can't be more than 15 inches from my nose...it's just hilarious if you ask me...if you want to do it that way, go for it! But really, just because you need 100 different things on a list to tell you how to dive (can you say "task loading?") don't think that's the "right" way, as in there is no other "right" way or every other way is wrong or inferior...very distasteful. Peace!
