Trey did improve his symmetry, his legs were too big before and overall it seems his arms and back have come up.
He shouldn't have bulked so much, it is stupid, it's what cost Kamali higher placings from 2002 onwards, he bulked up too much in 2002 and had to drop extremely fast for the Olympia ending up 7 pounds lighter than the previous year.
You can only add so much muscle, your body can only accept so many calories.
