Mark, as it seems, you didn't yet get a chance to try a BP/W as you didn't answer my question back there. Please do when you have the opportunity, perhaps you'll realize why some people are almost fanatical about it. I'm pretty much sold on it.
I for one will not go back to any jacket type BC, regardless of gimmicks or lack of. I don't really care how comfy they might look like on the surface, that is not their role, plus the 'comfy factor' acts like a magnet for more lead to sink it.
I find nothing uncomfortable about a single webbing harness or a steel/AL plate on my back, but do appreciate how it packs, requires less led on my belt and feels solid, not wobbly and doesn't ride up. If you feel the same about your ProQD, more power to you then.
The whole i3 thing I have a problem only as it presents itself as a solution for lack of skills, something that should be worked on not neglected by relying on a technology solution.
Merry xmas to you too!
