Last year was my first season playing on bent fairways... like you, living in Kansas pretty much means zoysia.
The fairways were pretty mushy last year in August, but I guess it's pretty hard to get the sprinklers turned off. I won't lie, I do miss the zoysia sometimes.
Brauer's Eagle Bend in Lawrence is switching fairways over to zoysia from what I would guess is a fescue mix (I'm no grass expert). They had a ton of trouble keeping the old fairways alive. It plays a lot different with the new grass. The fescue would run forever... especially late in the summer. The new fairways are nice to hit off of, but the fun of running the ball along the ground is pretty much gone.
