'Dr' Black, I wasn't aware that this was Miss Morris' spelling class. I am constantly amazed by your nonstop attacks about pushing the technical diving envelope. By your logic, Swede Momsen was the most dangerous diver of his time. In case you aren't familiar with Navy diving history, Swede was the Navy Lieutenant Commander who knew that helium was better than nitrogen for deep diving. He, too, used human test subjects to rove his theory. Time after time, his Navy divers got bent, but he continued. The final result was a set of empirically-derived tables that worked for Navy divers (but didn't guaranty that they wouldn't get bent). So now we have WKPP divers blowing through the NOAA ox tox limits by 20000%. What does this really say? To me, it says that taking back gas breaks dramatically reduces the toxicity of long-term exposure to O2. My guess is that Swede Momsen is smiling from the great deep dive in the sky over this discovery. Put in a way that you may be able to understand, it wasn't that long ago that cataract surgery patients had to have their heads and necks imobilized with sand bags to prevent post-surgical damage while healing. Now, cataract surgery is no-stitch, outpatient surgery. If somebody would have suggested in the 1950's that a laser could be used to correct vision defects by reshaping the cornea, they would have been given about as much respect as DAN gave the WKPP presenters concerning pulmonary ox tox. What's my point? My point is that open-minded people can change their perspective and learn from the pioneering efforts of other people. I am not one of the people who blindly follow George or JJ - although I could have saved a bunch of money by doing so. I have questioned everything they do at one time or another. I started out as a 'tech bc' wearing, long hose stuffing, uninformed diver. I, too, wanted to dive my way. One couldn't have too many D-Rings or too much lift (If you are reading this Tyler, please feel free to laugh in remembrance of my Intro Cave Class). Under the patient teaching of the likes of Tyler Moon, Pat Watson, and Jarrod Jablonski, I learned that their system worked. In fact, it worked better than anything that I could try to reinvent myself. I don't dive with the WKPP, and I'm not sure I will ever be of their calibre, but I have learned a lot about safe diving from them and I will continue to learn from them. You might want to open your mind and learn something, too. If I have misspelled anything or abused proper grammatical structure, I am sorry.
