Trying out a bunch of different kinds of handlebars on a single bike? It's a good way to spend a lot of money, and get a lot of experience as a mechanic, switching out stems, bars, shifters/brifters, and cables, and then adjusting everything before you think, "No, I think I'd rather try something else."
I'd suggest making a day trip to the nearest large city -- from western Kentucky, maybe Nashville, St. Louis, or Louisville? -- and hitting up a bunch of bike shops for test rides of whatever they have in stock. If you can do it in the middle of the week that'd be even better, since the shops' crews will have more time to work with you. And (if they have relevant models in stock) the bikes you ride will be set up and ready to ride, so you won't be trying to compare different bars with a day (or a week) between rides as you change everything out and re-adjust.
