Hoosier and Cameron are both 100 time easier than the so called 15% rollers in Missouri. Ozarks are pretty but hard constantly up and down hard all day. Cameron is mostly 4-5% until the top where there is a short section around 8-10% but overall, it is a very nice road and climb for my money. Hoosier in the other direction west to east has a few steep switchbacks, I have not ridden it east to west but the descent seemed pretty gentle and nothing special scenary wise.
