Hi Nick, There is no doubt that you can ride much faster with the Luxos and get much better illumination in contrast with the Cyo. However, I believe it would be less than adequate on a 40 mph descent because although the road may be illuminated, the hotspot will be off the road, and I would not be able to see hazards adequately. On the other hand, it is much better than going blind, which is what would happen with the Cyo. If you know the road is in good shape, then you could be ok...
The Luxos is not only bigger than the Cyo up and down but also front to back. If you mount the included bracket downwards, the back of the Luxos hits the mount and you cannot rotate the light high enough to orient the beam properly. Perhaps the mounting point could have been moved up on the bracket, but I didn't try. Also, as you mention, perhaps if the mount is bent, then the rear of the light might be able to orient up enough to mount properly. Maybe the Velo Orange mount would be fine...
