What's the focal length? About 550 mm? If so the shorter focal length eyepieces you list sound like rather high power. 50x per inch gives 160x. How high do you really want to go?

My suggestion would be to try each of your 3 eyepieces in the binoviewer, viewing with one eye. Decide which one gives the best view and get a second one of that.
