Hey Nashville Cat, Most any tire works on the Katy, people seem to get concerned when they are running those skinny little road tires, of which I don't know anything about. But, 28mm's and up no problem, some have run 25's I believe with no problems. I run 700c x 32's on touring bike and 700 x 38's on the hybrid they work very well, I really don't notice much difference. Carry a patch kit, you probably won't need it but just in case.
The Katy Trail is pretty smooth, Frisco Highline, not as smooth and with an occasional rut or two, it's not really too rough but a more challenging ride and also a lot of fun, I wouldn't use a road bike on it, hybrid or mountain bike or anything that is a little beefier than most road bikes.
Enjoy your ride!
