I don't really recommend going the Dragon DX route. If you're going to do Dragon, go with the Rogue or Mace. I had a pair of Dragon DX's and they were actually good for a non-spherical lens. The problem came from the overall longevity and design. It blocked my lower peripheral vision more than my current Oakley A-Frames. Also, the anti-fog coating on those did not last very long. Besides, spherical lenses are just superior to flat lenses. Not only is your view undistorted, but it is much clearer.
If you have a high budget, consider these...
Smith I/O or I/OS for smaller face
Electric EG 5
You can find good deals on last year's Oakley A-frames, just be warned that replacement lenses cost an arm and a leg from Oakley.
As for lens color, I personally like the Oakley Pink Iridium as an all around lens. Just go to the company you are purchasing from and look at their lens light transmission chart. More light transmission equals darker conditions. Less light transmission equals brighter conditions. Pick something in the middle.
If you go Smith, I find that their Ignitor lens is great for all-around.
