It reads strongly like you're trying to have it both ways. Any style of BC for diving purposes is very much _not_ a life jacket, and shouldn't be treated as one, nor be relied upon to be one.
A BPW is superior in every possible way for diving, and jackets are a relic of a the past. If you can't use a BPW properly, that's on you.
Superior according to who? You? What are your qualifications to make that statement? Can you apply your so called expertise to everybody? Besides, who said anything about jackets? I lump them right in with BPW's but not as bad at face planting.
As far as not being able to use a BPW properly: You're right. I can't. I paid an Instructor good money to teach me how to use one since I had a lot of trouble doing it myself. The teaching process was an abject failure. He said maybe it was my short legs or big shoulders and arms but even with lots of input from me and the Instructor, it face planted me so bad I almost drowned in the pool!.
I trained on a Horse Collar type BC back in the early seventies and still use it today. It does not face plant me. It does not squish me on a dive. It does not get in the way of anything. It does allow me to float calmly on the surface with no input. In other words, it will save my life if I'm unconscious on the surface or even just tired. I like it and will not change.
No, I'm not trying to get anyone to convert, just stop with the negative and/or derogatory comments to anybody who does not do something the way you think it should be done. I have dove in many oceans, rivers, lakes, rivers, canals and other assorted crap holes using my Horse Collar BC and been doing it for over fifty years. I have tried lots of different gear configurations. I'll keep using my Horse Collar BC. You use whatever works for you.
A joke to lighten things up:
Two SCUBA divers got separated from the boat and have been drifting for many many hours. One is wearing a Horse Collar BC and the other is wearing a BPW. How can you tell which is wearing what rig?
Easy! The one wearing the Horse Collar BC is snoring peacefully and dreaming of a steak dinner. The one wearing the BPW is desperately trying to balance while laying on top of his gear and wishing he had a Horse Collar BC!!! lol.
You can't deny Physics. Air floats on water and will always try to get on top. You can prevent it from doing that with constant input but it will continue to try.
