Jeff, my first yak was a Caper. While it is extremely stable it is a nightmare to attempt to  paddle it straight. It wants to wander no matter how good your paddle stroke is. I just met a female kayak angler that paddles a Venus and she told me that the Venus was the same way. Another choice is the Cobra Navigator. I had one and while longer than the Caper weighed exactly the same and was way better to paddle. I've got a buddy with a T-13 that likes his a lot.  I don't know anything about the T-11 which is another choice but I would definitely try to have your wife test paddle a few yaks before you settle on a Caper. jim
