When I was with Conway their dispatch seemed quite disorganized.
I did appreciate their open door policy, which allowed you to stop in the office when you were in Ann Arbor and talk with the people.
The biggest disadvantage at Conway was that if you went west of Chicago with a load, you almost always had to return to chicago for your next load. They had very regular runs from O'Hare Airport to Rochester, MN, and they had almost no return freight.
As a husband/wife team, if you have the minimum six months experience requirement, I would recommend Landstar Express America. They work through agents rather than central dispatch, but when you get used to the agents the Landstar is a better deal than Conway.
