Genuine q, dont think ive seen you condone chinacarbon before
I condone Chinese manufacturing when somebody has brand value they want to defend by doing QC. At this point, it looks like LightBicycle have that value, so one would hope they are interesting in preserving it.
Only if you're under 5'7" :)
LightBicycle do a 46mm deep × 21mm internal rim that I'm tempted by for my road bike, with a 130kg load rating it's enough even for me.
