Can't realy go wrong with a Flight Series, whatever the colour.
Pity Redline didn't have a UK importer last year when I got my lad his current Mini, otherwise he'd be on a Flight or a Proline instead of a DK Dart. The DK's alright (and to be honest, he doesn't race enough to justify having a better bike), but the Redline completes (especially the Flights) are top notch.
