Arkansas state route 123, Southeast of Jasper, AR (goes through Hasty and Mt. Judea) was my favorite road in that area after a few days of riding around there. AR 23 is great, but straight and boring compared to AR 123. Take AR 74 out of, or in to, Jasper.
Eureka Springs, Branson, and Table Rock Lake get all the attention, but are basically tourist traps. My wife likes' em, I dislike 'em. The roads south of Harrison, AR are narrower, curvier, and less crowded, and Harrison and Jasper are geared more to the Buffalo River than the tourist meccas North and West.
At the South end of this stretch of AR 123, you'll hit AR 16 which can take you West to AR 23. Where 16 hits 23 is mountains to the South and twisties to the North all the way to Eureka Springs.
AR 62 from Eureka Springs to Rogers is pretty good, too.
