No, I was not there.

The guys are having so much fun baiting you that some of the claims that
they are making are probably exagerations. This is a natural reaction to the
way that DIR is presented to them. Not as an alternative, but as the only
way!

A parallel which as just come to mind is the difference between a manual and
an automatic gearbox in your car (not even going to the semi-automatic or
tiptronic(tm) systems:-) ).

With the automatic gearbox (DIR) your input is limited to deciding if you
want to go faster or slower. You can relax and enjoy the trip, probably also
set the cruise control and watch the world outside your window.

A manual gearbox (Independants) means you have to watch all the time what
the road is doing: is there a hill coming, do you need to zip past this
truck in front of you, and you have to make decisions constantly. But these
decisions (for me at least) are in your muscle memory, you know what is
happening and why you changed gear, but did not have to think about it.

I never said we did not, but these things cost money, these things take
time. There is no way that any of us would stop diving until our kit was
exactly DIR and then restart from the begining. We are all still building up
our gear as we need it, and have priorities other than manifolds and long
hoses.

This is a holdover from our training courses where everyone used, and had
always used, independants with short hoses. The caves we dive either have no
restrictions (Wondergat) or very short restrictions (Badplaas), we do not
skooter anywhere.

We are open to ideas which come from outside the community that we dive
with, but we reserve the right to choose which to accept and which to think
a little longer about.

Enjoy,

Larry.
