Well, since I already have an MC2 Attitude I would go for the MC1 Backfire. I'm also not so much of a fan of the Storm paints but love the classic Backfire.
However, if the MC2 Adroit is Nightstorm, original colour and has got the 2inch downtube, I would opt for the MC2. In addition, the conditions seems to be better, too.
By the way, I am happy to take the MC1 Backfire off your hands if it is 20inch or bigger.
