Back when I was young and flexible, my rear view mirror was "ducking the head under the arm". These days, I use a Blackburn helmet-mounted mirror, and I swear by it. From the reviews, it seems that a lot of people swear at it, though. To be fair it did take some fiddling and getting used to. Do you use a mirror? If so, what kind?
with a Bikeye on my commuter as backup. The latter has it's uses, but is a bit awkward to use. 
Anyhow for the price this works fine and can see anything approaching from a good ways back.
