http://www.flickr.com/photos/shirokaras/sets/72157633253388934/Third time I've tried this... after using both FE and RID Bumblebee as bases to repaint into Jazz, I realized he needed something a LOT sleeker if he was to work.
Like a lotta people, I was really tempted to use Knockout's mold, but... I couldn't bring myself to like it enough, somehow.
Then Smokescreen came out.
Surprisingly enough, it works, and this is a pure repaint. I didn't remold the head [even though I was sorely tempted to], and it seems to work so far. Even though his visor is literally just paint.
... and with this color scheme, it's a huge reminder why most of us thought Smokescreen was either Jazz or Mirage when we first saw him...
