"Shrwdtech happens to be one who falls into that other category. All evidence points to the fact that he really belives that the regulators are not safe for up to 40% without an O2 "kit" and is not simply following the company line."
Some people here are correct. Many people speak only from repeating what they here. MikeF and I often have differing views on things but he is far from a "moron". He's informed and has thoughts based on his experience, knowledge and opinion.
And while I am not out to impress anybody, Sherwdtech is a NAUI Corse Director, an advanced Nitrox and Deep Air Instructor, as well having extensive experience in a field working with both Gaseous and Liquid Oxygen on an almost daily basis. Doesn't make me an expert by any means, but I'm betting it gives me a GREAT DEAL more experience than 95% of the people out there making posts on the subject.
I'm glad your reg and others have not "exploded", as you say. Wonderful to hear. Sincerely hope it never does. I hate reading about accidents to anybody or about ruined gear (more likely result). Not to mention I actually enjoy our discussions, James.
But, it still boils down to a game of Russian Roulette. There might be more than 6 chambers in your "gun", and you nor anybody you know may never be the unlucky ones, but it's going to happen. There is no way for us in the dive industry to know that the consumer is doing exactly what they are instructed to. Some play the odds, some decide to go a different route. Liability? Sure. You bet. .0000000000000000001% of a chance is still a chance, and we as a company have decided that it's still too much of a chance to take with somebody else's life, gear, etc.
Say what you will, point the fingers where you want. That's fine. Trying to make money off this? Our parts kits for this are around $4. There is no money to be made in an area of our sport that includes about 1% of the divers out there.
So, as has been said several times, do what you think is best.
Oh, and Split Fins. I've got one of the very first pairs of Apollo Bio fins to ever be sold, have had them in Alaska, British Columbia, The Pacific NW, California, Mexico, Caribbean, Florida, and Hawaii... and have yet to see any single fin out there give me a single reason to dive with anything but split fins. Enjoy your cramps and tired legs. That's your choice too.
