Amouzad just won 65kg final comfortably. He won silver at 65 at the Olympic and another gold 2 years previously. They say 65 is one of the toughest in terms of parity. I would say if you win 2 gold in 4 year and an Olympic silver so medalling 3 out of 4 years then you are doing something right. I wonder who has done some something to match him- Otoguro? Kiyooka? Mamedov?
I think with that track record he would want to stay at the weight as long as he can
