Actually I think his issue was with BP/W being the solution to every one of life's problems for some people. I have seen it with a couple people and just walked away from it.
I am just now moving to the "grown-up table" with a BP/W but have enjoyed every single one of my dives with my poodle jacket (even if I do look like a stroke ).
I dived a jacket BCD for 25 years and I'm so glad I did, without that experience I would never be able to appreciate my BP/W as much as I do.
