My girlfriend is about the same build as yours, and she says my GT is more comfortable than all other bikes she has ridden R1200CLC's, GS's, harleys. All I've done for adding to her comfort has been a Pirates lair backrest and an autocom. With her getting her own bike soon, I'm free to get a GS adventure (hence why my GT is for sale). If I could afford two bikes, I'd keep the GT for two-up. It is plenty sporty, and you can raise the pegs for a little harder riding, with lots of storage and many creature comforts.
