detroit diver once bubbled...
You were doing great until:
"That's the part I really have issues with. While it is true that a Hogarthian rig provides a level of simplicity, streamlining, and balance that enables the diver to more efficiently use the skills they possess, it doesn't inherently make anyone a better diver. Nor does it necessarily mean that anyone who doesn't dive that style is in any way less skilled, or less safe as a result."
This is precisely why you cannot seperate one piece of the DIR system and still be DIR. Equipment is only one SMALL part of the equation. It comprises a number of things, including team awareness, signalling, bouyancy and trim control, and a lot more. The rig does not make you a better diver, or a diver at all. But you said it yourself-it is simple, streamlined, and balanced. People get hung-up on the equipment thing, because it is so different from a typical BC. It's hard to understand why less is more unless you really try it.
