Bren Tierney:
Is solo-diving the most appropriate term for this aspect/style of diving?
Yes, in that it denotes a dive conducted by one diver. One individual person - alone, without others.
Is all 'solo-diving' self-sufficient diving?
Obviously not, though it should be.
Under the category of Solo, we have to accept all who dive this way, as described above. In the same way buddy diving must own up to those who practice it, correctly and incorrectly. Whether done safely or not, they still fall under their respective category. After all we need some basic, fundamental definitions.
A Solo diver who is not self sufficient is like a buddy diver who can not assist and count on assistance from his buddy. Both defeat the purpose and reason for being from a safety perspective, yet, they fit in their respective categories with perhaps a false sense of security.
One doesn't become self-sufficient overnight. Only when proficient in the basic fundamentals do we become self-sufficient in deed, not just in words or concepts, and can begin to expand and enhace its properties - in deed.
The learning curve always carries some unavoidable risk, yet, it's usually manageable and can be mitigated.
