I keep spell tomes, mehrunes razor, knights of the nine, and sometimes the orerry installed. But usually wind up disabling the others due well to the fact they are less content and more flash. sure the homes and such are nice.. but I wind up not using them as much as say the IC shack due to it's simple layout vs having to go through portals, tunnels and flaming hoops to reach storage that's usable.
Anyone else run into that mindset playing, where the lairs, towers, keep , etc just are not worth loading up
