A choice of mirrors is a matter of personal preferences. Many people like the handlebar-mounted mirror that sticks out the end of the left bar. I found that bike-mounted mirrors pick up all road vibrations and distort your view. Helmet-mounted mirrors are a good choice but you have to be careful how you care for your helmet after taking it off; these have less vibration than the bike-mounted mirrors. A third type is the eyeglass-mounted mirror (my preference). It has the least amount of vibration from road bumps and you move your eyes and head less to check the rear.
