Rob,
What youre experiencing is to be expected if youre going to go against the flow. A back plate and wings with a long hose is certainly not the mainstream configuration.
It will be difficult for many divers to accept a different configuration that is as good as if not better, than what theyre using. To do so requires that they reexamine their worldview. Thats why change is difficult.
If youre going to let the reactions like this bother you, theres a rough road ahead. No offense intended, but youre post does come across as a bit self-righteous and that may be making the situation worse. Ive found that if you just calmly explain the equipment configuration and go about diving everyone will come to except it. Good diving skills tend to be easily recognized and universally admired once you get in the water and will provide credibility to your gear configuration. If however you set out on a crusade to get everyone to acknowledge the superiority of your configuration, things wont go as well.
Good luck,
Mike
