Jason - get to work

Seriously though I have done my share of reading on carbon on RC and I can't find any literature that states that the ROX is 2x more effective. I would like somebody to prove me wrong so I don't have to keep reading about all these numbers linked to carbon.
On another note, I've only used regular carbon in the past 6-7 years and I've never tried this ROX which is suppose to be harder. But I've never had an issue with carbon dust with the regular carbon.
So does it being harder mean its more effective or harder means it doesn't create as much carbon dust?
