I look at BP/W an evolution in diving, most people start out unkowning and hit the OW class in a jacket style BC and you take in what they teach you, when you get out of class you usually go to that shop and buy equipment and dive dive dive or vacation dive, you never come accross anything different.
Then one day you come accross a cave diver and they have this wicked looking rig thats way different then anything you've ever seen so you start asking questions, get some ideas, hit the internet do some surfing in those areas and find out all kinds of stuff and start slowly trying it out until one day... your wearing jet fins and a BP setup, this was my route, I tried to stay open minded, tried back inflate BC's as opposed to the uncomfortable looking BP rig, then eventually went straight BP/w, tried different fins along the way, even *gasp* those dreaded split fins that were so bad they almost made me throw up under water (another story), the more I kept leaning into the standard BP/W setups the more I found they worked great, better, like evolution.
I've never seen a diver in a standard BP/W configuration hit the water and become a "reef walker" where as I've seen too many setups where I look accross the boat to a diver with a fancy vest with all kinds of doodads, guages dangling, octo dangling, ankle weights and split fins walking on coral when we hit the bottom.
Now dont' flame me I'm not saying everyone in a vest walks on coral, but my point there is most likely that diver has never been educated beyond OW, and yes they were walking on the coral foot in front of foot along the bottom, after I watched the end of the fin cause a small coral head to explode when he tried to step over it I couldn't look anymore.
I expect you will NEVER see a diver in a backplate and wing setup do this, why? Because you have to evolve WAY above OW to get into the areas that push these setups, OW divers use standard BC's and such because thats what those circles push, if OW classes were taught in BP/W setups I expect you would see a LOT more of them on the vacation diver market.
I'm a BP/W fan, but I didn't start that way and I didn't start in areas like in florida where these kinds of setups are common, I worked my way up to the setup trying out gear long the way, yes it cost me lots of money but in the end I know I didn't just jump on the BP wagon so I could be "cool" or look "techie" I tried lots of other gear that just didn't work as well and eventually ended up here.
