Thanks for the reply. My wife and I just finished our first 22 miles in the Burley rental. The owner of the shop spent about two hours fitting the bike to both of us, and it fitted both of us well (i am 6'0"). The only complaint on the burley it's that the stoker size on the rental (Medium frame) was almost too big for her. The stoker seat had to be down all the way in order to acomodate my wife size (5'5"). The Cannondale road 2 should be a better fit, as we are looking at a L/S frame. I won't be able to try a Cannondale, as I can't rent one, and I know aluminum can be a little harsher ride, I just hope its not too harsh for my wife.
