+1 clipless - I have old Sampson Stratics on one bike (there's no walking at all with those obnoxious cleats), Look or Look compatible on two others, and my 13yo just bought mtb SPD clipless for his Raleigh and loves them because he can walk around and it doesn't matter which side of the pedal is up when he goes to clip in.
I did see some Look compatible cleats with a slot for old style pedal with toeclips on Yellow Jersey and may order those for my older Peugeot and keep the toe clips.
