This might not be much help, but I change my mind on lights more often than I change my underwear.

I've had both on mine which is Crystal Blue, and both suit it down to the ground. I've got ambers front and rear at the mo, and if the mood takes me, I can refit my smoked and clear ones in 10 minutes. I'd suggest have both, and change them as the mood takes you.

Whatever you do, don't mix and match as it just looks nasty.
