BTW, my daughter thinks I'm the best daddy in the world.
On a technical note:
So Bartek, aside from pedal tension, one of the reasons I really like the Shimano design over Look (and old Shimano) is that the front of an spd -sl cleat actually engages below the platform of the pedal. This design helps prevent the pedal from releasing when pulling back since the nose of the cleat will actually hit the pedal body when pulling directly back. So you really can't even make a direct apples-to-apples comparison about pedal tension of the two systems. Not that I would use speed plays, but that also can't really be compared.
