Hey Seawolfdiving,
Yea, you techies have your mind right when it comes to thinking ahead with plans B and C ready to go.
Looking back, I wish that my PADI dive training focused more on real life emergencies and the need for redundant systems. Also, I wish I did not have to read books and tech diving manuals to prove my suspicion that all dives are decompression dives.
My instructor is an extremely experienced commercial diver, but he had to "tow" the PADI line when it came to teaching us "no decompression" diving and the buddy dive partnership system even though three of us in the class kept getting him off track with philosophical questions about decompression and the falicy of relying on the PADI buddy system for total safety.
I will probably never go techy as my mind is not suited for staged decompression regimens. I would get bored, make a gas switch mistake, and be sucking pure oxygen at 100’. I know my limitations.
