Im thinking this springs CUSA tourney had a 9lb sack from the buck brush boys was the heaviest I can remember. Then this tournament with penn/brozio at 9.21 and Father and I in same tournament a couple years ago at 9.47 are the only ones over 9 I can think of recently. Not sure about 8lb sacks... and I could be wrong about this spring but im thinkin that was it?
