Okay, newbie question. I am considering going the next step and moving towards a more advanced pedal system. I just purchased a used 520 that has a normal platform on one side of the pedal and a clip for a cleat on the other side. Since I have never ridden with a clipped in cleat, I am worried that I might not get unclipped fast enough in order to set my feet on the ground. There is I also the whole shoe cost question as I have noticed several different styles.

The other consideration is a pedal with a toe clip. This seems a bit safer, but is it as efficient as a cleat? As I have never ridden with either options, I really do not know what I will be gaining with either system. Any pro / con opinions?
