I have double sided pedals (not these particular ones) and I love them.
Sometimes I clip in, sometimes I don't. And my favorite way of biking these days is to clip in on my right side, but not on my left, since that is the side I always step down on when I stop my bike.
My left one is so much harder for me to clip out of, and I get really nervous that I am going to fall when I stop, since it is not natural for me to put down my right foot. So I leave my right foot clipped in when I stop and just take my left foot out of my basket.
And if I feel like practicing on a flat road, I clip in both pedals, and then if I can't get my left one out in time, I force myself to unclip on my right side, and step down, even if it feels awkward.
I'm not sure whay my left one is so much harder to do. It is set at the easiest setting. Maybe I just don't have the strength in my left ankle? But for whatever the reason, until I am comfortable on both sides, I love having the option of clipping in or not
