I use a Magicshine on a helmet mount to see and quickly flash oncoming cars and cars on side streets, very bright. Then I use a Planet Bike Blaze 1 watt on flash mode as an extra be-seen light on front. It's really easy to outrun the cheaper less bright lights light the PB Blaze riding 15-20 mph. I'd go for the more expensive Cygolite out of the original list.
