They are on my list, Zac! I caught something this year that was either a female redear, or a hybrid redear... still looking for a bonafide pure redear.
I've heard small nymph or scud patterns under indicators near the bottom work well. Obviously the spawning season would be the best time to find them in a predictable, accessible location (in the shallows near shore), otherwise, they are often in deeper water. Later in the season, look near the deep side of weed eges.
In the archived panfish articles on FAOL, there was a guy (his name escapes me at the moment) who would fly fish from a canoe (not Rick Z), and catch redears mixed in with the bluegills... even on dry flies.
