Either...
A) Classic Rock (they're basically that now)
or
B) Something else
Mind you, 103.1 has NASCAR races for the area. Doubt that would do well on anything besides a country, sports, or classic rock station...and that's too lucrative of a contract to chuck away here in the south.
Plus, Big 98 is basically still oldies. You might get a Skynyrd song mixed in on occasion, but its still an oldies station in classic hits clothes...just like 103.1 is a classic rock station in classic hits clothes.
