If catching smallmouth is your goal then I would pick Cumberland. On April 14 smallmouth should be in different stages of spawning. The early spawners will be done and the late spawners will be getting ready...find a bank with pea gravel, clay or a sandy bottom. Chuck rock would also be a plus. Some of the deep cuts have silt in them from runnoff so if you can find something like that then I would also give it a try.
