So after a year of DE shaving, I've given up. So, I decided to go back and try the fusion which had given me such terrible irritation and had driven me to find B&B. However, with a brush and soap and proper technique I got the absolute best shave of my life. Still, the fusion blades are way too expensive. So, I'm looking for a cheaper alternative. I can't decide between the Atra or the Trac II. I've heard that the Personna cartridges for the Atra and Sensor are the same blades with different attachment parts to make them fit the different handles. Is this true? Also, for those of you who use them, which do you like better? The pivoting Atra or the fixed head Trac II?
