I ended up using the 110 stem of my old racer, and adding a Dia-compe hanger, now she fits both myself and my stoker well...
The only thing I plan on now is new bottle cages, and Brooks saddles! I do think I'm going to order the DaVinci cranks for the stoker to give us a little more freedom of adjustment, I'm used to a high spin rate and my stoker could stand to have shorter cranks anyway....
