David,
The DIR continous webbing is easy to get out of and works in all =
situations. I used to have trouble getting out of mine but realized that I =
had my harness too tight. After loosening it I was able to get into it and =
remove it quickly without assistance, It also didn't restrict breathing as =
the too tight harness did. The buckle process you describe below sounds =
like a workable compromise in some situations but it is just that- a =
compromise. I can imagine several scenarios (cave restrictions, scootering,=
handling emergencies, etc) where I would not want the buckle to come =
loose even if it didn't go anwhere. The problem really starts compounding =
when you try to restow the loop (just like the CF that occurs when you =
need to restow a stuffed long hose).=20
I am amazed how the internet has become an almost instantaneous =
global peer review. This is a good thing. Like a scientific journal, a new =
standard ("paradigm" if you can stand hearing that word just once more) =
can be presented and debated. Unfortunately, many people (I'm not saying =
"you") believe that DIR was thought up one night over a couple of beers. =
This couldn't be farther from the truth. Much of DIR had it's origins in =
accident analysis then evolved to fine tuning the main ideas as a result =
of incident analysis. For example: When some support divers had difficulty =
understanding George's hand signals at depth the EAD was raised from 130' =
to 100'. The accelerated deco that we do was a long process of discussing =
previous dive results with the top physiology gurus and examining ways to =
incorporate theory with results. This was a slow process of an educated =
pushing of the envelope which was validated by George, JJ, Brent, et al, =
before being passed to the rest of the team. What we do has raised the =
interest of many researchers, in part, because the informed consent and =
prohibition against doing what is perceived as dangerous procedures on =
volunteers would prohibit doing the experimentation we have already done. =
To answer another member of this list, yes, we *are* re-writing the book. =
By the time a technique is posted to the list by the WKPP it has generally =
been tried and proven within the team and also adopted by some internationa=
l affiliates. So far, I have seen no valid criticism of any DIR procedure. =
It is in use globally in every conceivable kind of diving. If for some =
reason it doesn't work in a particular case then insure that you are =
configured correctly (i.e., the harness isn't too tight to begin with). =
None of these procedures are patented or copyrighted (OK, maybe some of =
the GUE stuff is copyrighted). The WKPP is not in "the business" of =
selling equipment or instruction. The information is all free for the =
taking and most of it is much less expensive than what the monkeys in =
Gooberville want to sell.

P.S. My contact information is in my signature line- always has been, =
always will be. I don't respond to email that doesn't have a valid =
signature. Thanks for listening.

Then a crusty old engineer chimed in with a compromise: you dont need to
break the webbing to make it easier to ditch, you just need to make one =
arm
strap a bit longer. Therefore, catch a short loop of webbing in a quick
release down the bottom of the strap on the left hand side , leaving it
tucked away to avoid snag hazards. As long as the loop is not too long (6 =
or
8 inches is ample), even if it does release by itself its no big problem,
and if you were dealing with something else you could afford to ignore it
until the emergency had passed.=20
