Please allow me revise my statement to maybe make it more clear. When I said I "looked" at them, I should have said I investigated them. Visual appearance of them is unimportant to me. I am only interested in how something performs and that it does the job I require it to do. I have no doubt that in an extreme enviroment a BP is the way to go. However, in the type of diving that I do, it's "advantages" become unimportant at best and a nuisance at worst.
For example, you imply that a BP is safer than my Ranger. Given the type of diving I do, exactly how is it safer? Very few diving deaths are caused by malfunctioning BC's. Of these I suspect a stuck inflater valve is the most commom malfunction on BC's of either type and both have similar type valves. The failure rate should be the same. Or is it the quick releases on the shoulder straps? I have yet to see one fail, although I am positive one has, but even if it did, I only see it as a minor problem. To me at least, the advantages of them vastly outweigh the possibility (and consiquences) of one failing. I can change the strap adjustment on my BC very quickly, say when I decide the wetsuit I have on is too hot/cold and change it. Unless I don't understand how the strapping on a BP works (and I have an old style one in frount of me), it's going to take a lot more time to re-adjust it.
Commonality? If someone can't figure out my weight system and my octo in less than 30 seconds, I don't want them as a buddy. Oh and by the way, I do dive with my octo in a necklace, that makes sence to me. On the other hand, if I were diving caves (I am cavern cert) where siltout was a possibility, I would want to have identical equipment. It just does not happen where I dive.
Simplicity. There are times that this make sence and times it does not. I drive an automatic car because I don't like to change gears. It is not nearly as simple a system as a manual transmission and has a greater possibility to fail but I have tow trucks and repair shops close by so the consiquences of failure are minimul, I accept the risk for the reward of not having to shift gears. If I lived in the outback I would have a manual transmision because they are more robust and less likely to fail. In addition, as the repair shop would be much farther off the consiquences of it failing are much greater. I see the BC in a similar light, the consiquences of a BC failure 1/2 mile back in a cave is grave, at 25 ft in a warm reef, its a nuisance.
I fully understand the logic behind the BP and agree that in more extreme diving it is the way to go. I guess what I have trouble understanding is why BP users seem to not understand that some of us don't do that type of diving and we want/like the other options that are avalible to us on other types of BC's. They also refuse to accept that given our diving style, our BC's are as safe, comfortable and enjoyable to us as theirs are to them.
In all fairness, I already have plans to test dive a BP when the water warms up some. One of the board members has offered to loan me his to try.
And you wonder why I have been staying out of this discussion.
