Thank you all for your various responses and opinions. Interesting that with all the technology and advances, Shimano SPD is still the crowd favorite ( as is mine, and I am a dinosaur). Completely forgot about the Speedplay option. Will most likely go with SPD, as I have a few older sets laying around that mimic the current Saint design, a nice platform that you can stand on, if you either miss a clip or don't want to be clipped in. Yes there is a slight weight penalty, but we aren't battling for WC or weight weenie wins.
As for if I'm "pressuring" her into this...hardly, it was her idea, her decision and choice. She knows she will fall (most likely at a ridiculously slow speed or stop). If she doesn't like them, no big deal, she can go back to flats, and I glue the rubber plug back under the shoes we bought her.
