hehehe, cute.

yeah, i am familiar w/the rule of 1/3's; typically
it applies to those doing wreck penetrations or
caves, but it has been applied to open ocean as well.
for your information, 'dir' advocates against
using a pony bottle as a source for redundant
air (or at least they did a year ago).
so, that's why i asked you why 'dir' would not
'allow' the use of one--especially when they
strap an extra argon tank for their drysuits.
in my case, i would not use an argon pony bottle
for my drysuit, but i would use a redundant
air source for myself or others, so there is no
net gain or loss there in carrying equipment.
there's nothing especially taxing about carrying a
pony bottle--especially when others who want extra
air take DOUBLE TANKS w/them instead of one single tank.
as far as maintenance, i already own one steel tank
and am in the market for another. a small
sized pony is no big thing on top of that--kinda
like doing maintenance on two regs instead of one.
as for attaching a pony to one's back, one can
sling it just like the tekers/cavers sling bottles
under their arm, no biggie there again--and my
pony is smaller than theirs.
as for lulling myself into a false sense of
security, that's been my point when it comes
to relying on another diver. also, since i have
to put more thought and effort into a pony instead
of relying on someone else, i'm NOT going to
be lulled into anything--it can only make me
more alert.
see? you and i can deal w/the same issue in
a different way: neither is bad or wrong or
inconvenient than the other...it's just different...
now do you get it...?...
"...a pony bottle for the average recreational dive becomes redundant."
that's why it's called a 'redundant air source'--it's
supposed to be redundant.
