ZKY:My design is entirely different and a completely new concept. Nobody makes anything remotely close. If they begin to imitate it, then I will know I hit the mark. But you know what, I'll always be the first one to have made it.
The market I'm after is the single tank recreational diver that has no interest in doubles but wants to dive minimalistically and enjoy the freedom of getting away from jacket bc's and loves the fit, comfort, and ultimate streamlining of my new system.

I am not sure that it is that original. The Mark Meadows Low Profile Backplate has been around for years

as has been the Oxycheq LP BP.
Both of them are light-weight stainless steel and put the tank right between the shoulder blades.
The only difference I see in yours is the bend, which could be actually troublesome for different sized people.
Both of the above mentioned items are of high quality handcrafted right here in the US.
So welcome to the pool
