It has been a long time since I rode in Iowa, but I doubt the roads have gotten better since I did. I doubt you will pick up much speed by going to 32 over 40mm tires. And you certainly will lose speed on the gravel. I have ridden gravel on 32mm tires and it's not great. I don't see the weight being that much of a difference even if you sprint to every town limit sign.
