Papa Bear - I agree that it's good to know that you won't panic in a zero-vis condition. We don't always know how we will react to different situations, and I will say that I was happy to learn that it didn't bother me, at least in terms of maintaining my self-control and remembering my training. I have been on dives that started out with decent vis, but dropped to zero at some point, due to something like finning up next to a reef with surge, or getting stuck behind a team of noobs who silted up the place. I never felt the slightest bit uncomfortable - I just calmly did what I had to do.
However, I guess for me, I just don't see the point in doing a zero-vis dive. I know others, though, who consider EVERY dive of value, even if all they do is skills-and-drills in a blackout. Not me...not anymore, anyway. I used to be more rabid about diving - as long as I was underwater, I was happy. These days it's just not worth it to me. No vis = let's go have breakfast instead!
Same thing with surf. I used to have a much higher tolerance for doing surf entries, and if I went to all the trouble to load up my gear and head to the beach, then I was going in unless the surf looked downright unmanageable. These days, if it's much above ankle-slappers, I'm outa there.
