now i know you're full of shit, 405 is not "weak" for anyone even a 500lb. plus bencher, even guys who bench 500 plus have to dig down and concentrate with 405, there is NO WAY that you've benched 4 plates for a double, post your picture and ask people what they think.
Anyone under 250 and natural, 405 is great, so for once I agree with you. However, for someone like Kaz, which is arguably a bad comparison, 405 would be weak. He was also one of the greatest of all time and over 300 lbs though.
