I tried it in an open room on both omni and cardioid, and I preferred the sound of omni for some reason. Anything I put through this mic sounds insane, and I haven't added any eq or anything. I'm still not sure when to use each setting though, especially figure 8. I tried it with two singers, one on each side, and I don't see the point of doing that. Thanks again to everyone who helped me pick out the mic!
