Better the devil you know

Ok, so have been thinking of getting rid of dark angel, getting him a one way ticket to Siberia etc. I am seriously thinking about going to get a nice Bhuddist person in or someone similar who can tell me what I can do. However, what if I get rid of dark angel and get light satan, or worse still, dark satan with ax extra dash of fire? What to do? Answers on a postcard please!
