The gear is a big factor with squats vs. deads. Right now, my best raw squat is about 500 and my best raw DL is 535. With gear, squat 550 range, dead 535. haha. I also notice that my squat suffers a lot when I lose weight, and thus, midsection size. I think that the body has a natural peak for deadlifting, while you can up the squat pretty much endlessly. I've been stuck at this dead weight for a few years now.
