The deadlift is one of the purest test of strength/ suits, shirts and raps don't do very much. If you look at the top 100 in PLUSA there 30 800 pound squaters compared to 1 deadlifter. There are a few men now in the 900 + range and 1 doing 1000. I watched this video of this russian strongman competitor on youtube. The guy did a 440 lbs hang snatch/ the guy also deads in the mid 900's .
