I have always thought of rack pulls, deficit pulls, snatch grip, speed pulls etc, as tools to help bust out of sticking points ot form points.
I have also come to believe that pulling both Sumo and Conventional compliment each other well to help improve overall strength. I will be doing both styles from now on along with some deficit pulls.
I am also with Steve that pulling heavy too often is not the way to go for most of us. I was doing that for a time and it just killed me and never did bring me closer to 500.
