Switching Pedal Styles-Need Advice

[pll]

Stick with what you know best and feel the most comfortable with.

I started out with the Look pedals and can now clip in without effort, but I would not make the change before a race.

+1. Don't change before the race. I have Look Keo 2 Max and love them, I had SPDs before. There is a learning curve to clip in, as the Look pedal is one sided. In addition, you may have to change to road shoes.
