Agree with what most have said here. When I learned on clipless (many, many moons ago), I was one of those people that never had a "clipless pedal fall". This may be you, as well! Do go with a dual-sided pedal. Everyone is different, but I have been using the SPDs for years - they are reliable (I know I am getting out of them when I need to) and easy to use.

FWIW, I broke my ankle last year. As soon as I was back on my bike, I was back to clipless pedals and didn't have any issues.

Don't be afraid!
