I've done thousands of solo dives starting with my very first one in the winter of 1961-62 (we only had one set of gear). One thing I do NOT do is recommend solo diving to anyone else. Why? Because I very rarely know what I consider to be the most important fact in determining whether a person should dive solo... their response to unexpected emergencies. If one panics in such situations, no way should they be solo diving IMHO.
Even for those who would never consider diving solo, I think training in self reliant diving is a good idea.
