At this stage I'm more focused on what the various certifying agencies say about solo diving in overhead environments.
The NACD says something along the lines of:
"The NACD does not condemn nor condone solo diving" i.e You're a big boy now. Make your own mind up.
(I would add that, IMHO, cave training does put the diver in a position where they have the knowledge to make an informed opinion. Gas planning and redundant gear is a way of life by then)
