Black Flash - I love them , my first Flash (back in the day) was black, always bought praise when folks were around.
Now I'm in a similar position to Sam, one of them has to go, the gold one when I get the front mudguard painted yet again (don't ask), will still have the Red version to faf about on and with tho, yes Sam I though of asking 5 grand but my mate reckoned I should ask 6 (you can come down, you can't go up tho), I reckon yours looks good enough to ask 6 - good luck with it
