WSM or KDF both would have a great SHOCK factor of flipping, so everyone would know about it, compared to if 97.1 changed again. KDF is putting up a great fight against 98 for #1 (and winning some) and WSM has some momentum and sounds the best in town in my opinion with their 90's to now format and promotion of the call letters. Sure it makes sense for one to flip, but you know the saying, "if it aint broke, don't fix it." If one was to flip, what's to keep all the listeners to going to 98 instead of the other cumulus station? Plus, many country listeners listen to ALL 3 FM country stations as is.
...and it all comes back to Star97. I think Mix anticipated Star to pickup oldies. Good short term move for Cumulus, but where would Star 97 be today? Where were the ads last week? "Not ready for Christmas music? Celebrate Thanksgiving with (insert new AC station here)."
I guess I'll just enjoy 1560 WMRO while I can (seriously, other than WHOP, that's the ONLY AC station with decent reception NE of town, be it AM). I like 105.3 out of Glasgow that I can get at my house, but not on the road.
