Thanks man...well most people think I am crazy but I used 2 main techniques to improve my DL. ..The first technique is pretty standard. .. I ran max effort singles to get a that days max and then start my sets at 80% of that max for 10, then 8, then failure to max again. I did this twice a week. the second technique is what people say is crazy. I would drop set from max without stopping until I reached 135 lbs on the bar. I did this once every 5 deadlift workouts...not sure if it will work for you but it helped me....be careful of those drop sets so you don't injure yourself.
