Seriously?
OK, start calling every dive shop in the directory across the continental US and buy a used ScubaPro "Classic" vest out of worn-out rental stock for peanuts. You won't die.
You will float like a cork on the surface and will have rather nice dives below the waves to.
Now you have something to compare "back inflate" to. Dive it, become one with it. Seriously, and I actually meant it.
Then:
There is a fifth dimension beyond that which is known to man. It is a dimension as vast as space and as timeless as infinity. It is the middle ground between light and shadow, between science and superstition, and it lies between the pit of man’s fears, and the summit of his knowledge. This is the dimension of imagination. It is an area which we call ... Backplate and wing.
I concur with this recommendation. The classic is hard to beat. Take a look at the amount of buoyancy it can provide. It also is great at the surface, where the wing will try to keep you face down in the water. Get to know the classic and then dabble with the wing. I tried the wing, it is a lot of bother and you have a crotch strap. If you feel the need to be in the cool club go for it, but I have been diving classics since I moved up to a heavier 95 steel.
