Too bad you don't wear a rear view mirror - or have one on your handlebars - then you wouldn't have to turn your head to see traffic behind you!
Any chance you could pick one up before Sunday and give it a try? I can't live without my Take-a-Look (glasses-mounted mirror). I never have to turn to look behind me and risk losing my line, and I can always see everything coming up behind me. It's a godsend.
Good luck!
