Poll: Triangle Or No Triangle Options

I am looking for people to share why they prefer to use or not use a triangle. I know some do and some do only once in a while. So share why you do or don't.

"I think I remember something about Aliester Crowley putting himself into the triangle while an apprentice called forth a demon from the circle Apparently while the demon used Aliester as a vehicle he was telling the apprentice all sorts of information"

"Also in response to Angalor, yes the spirit's name was Chroronzon, and when Crowley entered the circle, it possessed him. After that it tried to seduce and trick him into leaving the circle but he ignored it. But while Neuremberg was taking down the notes, the demon, through Crowley threw sand on the circle and attacked him, but was later pushed out of the circle and threatened with Neuremberg's magic dagger."

From whence comes these cockamame versions pls. ?
I've always enjoyed this story as a triune of persons ie. Crowley, Neuremberg, & Chronzon.
Nuremberg Evoked Chronzon to visibility via. 3 slain pigeons whilst Mr. Crow , hood drawn, stood apart in His own Circle Astrally identifying Himself with Chronzons' every facet--- not that he himself was in the Triangle.
