I don't know if any of you guys have actually noticed that in fact red just seems faster, black is more sexy and stealthy but silver is defo the sharper and quicker of the old box eye bastards. Can't comment on the fox eye 600's "colour-speed" ratios as I have never owned one (After a box eye it seems like a step backwards).
Strange tho is the fact that silver gen 1's are not so fast, it seems that with the bigger brothers then blue is by far the faster hue, I am talking of course about the earlier galaxy blue and not the awful dull midnight blue that appeared just before the gen 1's were replaced by inferior machines.
