Just read back and realised I put the X9 - just changed it now. You're right though mixed it up with the Cobalt X6. It did used to be the X9 though, the X6 which used to be half of the current X8 and after that the 56 which is now partly the 54. The X6, X8 and X9 numbers haven't half got around in the last decade or so.
