The M505s would be easier to learn on as they are double-sided. The advantage of the A520s is that there is some support outside the cleat which, when using MTB shoes that tend to be less stiff, helps to prevent hot spots. The down side is you have to get the right side up to clip in. Just lube the M505s up and set the tension to its lowest setting and go for it.
