I'm sorry, it's very clear from the second shot that the tank is lop-sided. You don't need to be a GUE instructor to see that.
As is the 1st stage preventing the head from coming upright, and the plate digging into the butt.
I'm really surprised this discussion has struck so many nerves, and is such a sensitive topic.
I started the thread merely to suggest that perhaps a BP/W may not be the right recommendation for all recreational divers, because of the potential problems they might encounter.
It's as if I've insulted someone's religion or something....
I think the bigger issue is that it is the way you put it out there. What I have read you make it sound like BPW has problems XYZ and all other BDC's do not have these same issues. ALL BCD's have advantages and disadvantages. ALL take time to fit "properly". Most of your arguments "against" BPW apply to all BCD's so it is hard to see the point. A poorly fitting "jacket" BCD is no better then poor fitting BPW.
No, a BPW is not for all, but it is not nearly as complicated as you make it sound. It reminds me of the commercials during late night tv. They show people who act like doing simple tasks are so complicated the average person can't do it and then show you some product that will "make it all better".
