A thinking man's deco line?  Think about this:  Use a live boat and
dive with sufficient surface support.  Shoot a bag and deco under that,
while your surface support follows you.  They can send in support
divers to assist and monitor you.  Doing a drifting deco minimizes the
diver's anxiety and level of physical exertion in any sort of current,
leading to a cleaner and more efficient decompression.  It also
prevents fatigue from holding on to a line for the duration of your
deco, without necessitating extra gear such as Jon lines.  This method
utilizes only the lift bag and an ascent reel of synthetic line, which
will not degrade and present the possibility of failing at the worst
possible time such as is the case with natural fibers.  You don't need
to tie into a wreck for ascent, and thus avoid cluttering the site with
line.  The line in this case does not bear any load, and so does not
need to be 1/4 inch or anywhere near that large, and so can be stowed
on a relatively compact reel which helps keep the drag down.  You can
deploy using only one hand if necessary, allowing you to still use your
light for signalling during the ascent.

I am a strong opponent of souvenir hunting, but do not wish to argue
further on that point.  From the perspective of having to carry mission
specific tools for a given objective, I prefer to stow these items in a
horizontal orientation, clipped off to the rear crotch d-ring and held
tight to the bottom of the backplate by surgical tubing loops. 
Anything that is too large, and by that I mean anything that presents
an entrapment hazard or that noticeably affects my drag in the water,
or that is simply too heavy, goes in a separate tool bin supported by
its own lift bag.

Try DIR.  If you go back, I will be genuinely surprised.
