SOS is right the clipless one side (platform the other) are a bit of a pain as you have to roll them over with your toe to clip in.

MKS makes quick release pedals (no wrench, pull back a ring and off comes the pedal). Buy two pair; one clipless and one platform then just switch them as the ride demands. Good for deterring theft too as you can take your pedals with you when you lock up your bike.
