Mike,

>>I would agree with this unless of course you are diving them because 
you are doing training dives in weenie conditions. I'm speaking of 
the doubles here. Diving a less is best hogarth rig with single 
tanks, long hose, etc... IMO, is a good thing for any dive.<<

That's of course how I started diving doubles. Doing the weenie dives to get
used to the equipment. After doing that for a while I found the rig actually
more comfortable than a single tank, mainly because of the stability and the
added redundancy - reg freezing is always a concern here, even in Summer, below
the 2nd or 3rd thermocline at 70-100 feet, depending on the lake. Below that
it's usually 4C all year.

I currently use double 12 l steels which weigh about 27kg with valves, not all
that heavy, and they save weight on the belt, although they are not negative
empty. I'll add a V-weight soon.

Also, on some of our local weenie dives, doing two dives on one single 12 l tank
sometimes gets me a bit low on reserves, but doing three weenies on the doubles
is no problem.
