How Hot Was Erica Roby In This Film?

Okay admit it, the high point of this film was seeing the lovely Miss Erica Roby stripped naked and having herself some hot lesbian loving with the pod person Sarah. So on a scale of 1 to 10, 10 being highest, 1 being lowest, and 5 being average, where would you rate Erica Roby's hotness? I'd say she's at least a 7.5 on the hotness scale. What say the rest of you?
