I'm going to have to give use of the hooka rig some thought.  Since I won't
have the ability to view contents during the dive, I'm going to have to be a
bit careful about my time and depth.  I know my normal SAC, but it's bound
to be different when pulling a kayak, without the drag of my normal kit,
etc.  I'm also going to have to give some thought to the possibility of
somebody coming along and turning my gas off for me.  Even as a joke, that
could create a problem.  I may wind up with a small pony bottle yet.
