Me, I'd snap in two. Had a guy last year at our gym who did 8 plates, looking pretty good doing it. Apparently in the hunt to beat the Canadian record, which if I remember correctly, was 780-90lbs? I asked him about training routines and he said, 'I don't do sets; I train movements,' and that's where he lost me.
