Rough country roads (if that's what you mean) = I personally like 700x28s. They're fast enough when it's smooth, but give you confidence when you're forced to hug the junk on the shoulder. Also handy for the occasional unpaved roads you'll come across in a rural area. YMMV.
If you don't have clearance for 28s, then yeah, 700x25 next best thing.
