My personal fave is to mount the light off the leading edge of my front rack. That puts it far enough forward to keep from getting any wheel shadows, and keeps it low enough from blinding oncoming traffic. (Although, with the Cyo you shouldn't have that concern with the horizontal cutoff optics)
IMHO best option. I have one bike with a mid blade fork mount, and I have seen people mount them down near the hub for the best lighting on the roadway itself.
