I would like to try out but I am in doubt whether I set this up correctly. 
From what I understand I place a cardiod mic aimed at the center of the sound. As close as possible to that mic I place another figure 8 mic recording the sides. I record both signals. I copy the figure 8 track to another track and phase shift it. I pan the figure 8 tracks hard LR. I ie take the cardiod mic up to 0 Db and then slowly fade in the fig 8s until I find the right balance where I have the width that I prefer.
What am I doing wrong, all I get is the R side (the phaseshifted one) phases out the cardiod so the R side is more or less silent when listening back to the combined 3 track signal. This makes perfect sense to me since the mics are so close together that they certainly share a lot of the transients. 
I am doing something wrong or does it have something to do with the fact that I record in neutral rooms where frequencies are fairly similar in all directions and with little "room" sound.
