I forgot to answer the question...
I pulled 170kg (376lbs) back in December 2012, and I guess could have pulled a little more as I was PR testing and wasted a lot of energy on lighter attempts. I haven't trained the deadlift for more than a couple of months consecutively ever since. That's partly because of injuries and partly because of my lifestyle- I am not usually in one place for more than 3-5 weeks at a time and sometimes I might be in a plane 5-6 times in a month. So nowadays it is less than that.
I pull in the normal way: get tight, straighten your legs until the bar comes to the knees without your ass shooting up, then push your hips through. The only thing that is slightly different is that to setup I break at the knees and the hips, like an Oly lifter, not just at the hips. Once I am in position I then raise my hips to more or less as high as I can go without bending my back. I just like that as a starting position- tight, and my back is really straight.
