MO 175 is very nice, especially south of 76 to the ferry crossing of Bull Shoals Lake. If you want to make this especially good I'd swing a bit further east and link in Push Mountain (341) down to 14. My-o-my, they put this gorgeous road in for motorcyclists only (virtually no traffic but seemingly endless curves!)
Large parts of this route are among my most favorite in southern Missouri. A good bit of traffic by Nixa but otherwise a great ride.
Great Long Day Ride or break up with stay at "The Hub", Marble Falls, AR
