Unfortunately for you it appears Lexington Kentucky will no longer be on 77. They added them to 61.5 and best guess is they will be removed from 77. Also bad news there will be no guide data on 119 because those locals are not on that ARC.
For long term stability, it would appear your best bet is go with SD locals from NY and/or San Francisco with AAD from 119 and add 110 for the most programming you can get. There will be a few channels in HD if your program package gets them, such as USA, SYFI, HBO on 300, TNT, ESPN on 140 and probably whatever local Sports (RSN) there is. There's one or two more from packages like BB.
If you add 110, you will also get in HD depending on your package, COOK, DIY, STYLE, HIST2, Hallmark Movie Channel, AMERICA(Channel 194) Velocity (Not sure if in BB still or a regular package) Universal Movies in BB, CI channel, Showtime East, TMC East, Encore East, Starz West, SONY and PIXL in BB, FOX Soccer.
I probably missed a couple, and remember some are in additional packages like BB and obviously some like HBO etc are in the premium movie packages.
