To convert to discs or not convert? That is the question!

I almost totalled my 61 Cadillac 2dr HT in stop and go traffic when I made a legal left hand turn and a yahoo ran a red light due to my brake fade. I immediately parked and ordered a kit, stops on a dime. I am doing the same to my 63 Valiant Convt as well. The price of the swap is so small in comparison to an accident.
