did you put that copper on a scale ??
can you paint caps. from silver to black to make them better?
can you test this board for 2hrs and that board for 20hrs and claim its better?
unless I see the specs on the parts to look up at the manufgacture to see if one has a 20 amp part and the black has a 30 amp part I got to lean twards hype
just like gigabyte lied about the vrms on there ultradurable boards the folks that pullrd the sinks off and looked found that the vrms claimed to be used were not on there boards
