After a close call with a motorist who looked directly at me and my MiNewt 600 (on medium) and still didn't see me, I went to the parts bin and pulled out my old MagicShine. Now I run the MS on SOS flash and keep the MiNEwt on medium. I can definitely see a difference in how cars notice and react to me. My next move is to mount my Blaze 2W on my helmet to shine at cars approaching from the side streets. I haven't decided if its going to be on hi or superflash.
