rockel should have won easily
He has no back, especially when placed next to Moe.
I like Moe the best (time for me to eat crow), from these shots, though Silvio has the thicker chest in comparison- what also doesn't help is that Moe faces away from Silvio somewhat not wanting to go head-to-head with him to compare the pose.
I think Rockell is the best from the front, but the poor guy turns around and pretty much disappears. His lats are weak, but he has a decent lower back. Since he's standing next to Moe, who has a very thick back, it's very obvious. He's also standing next to Hide, who doesn't look like he's got a bad back when placed next to Ronny, but if they shifted the line-up a bit more, maybe the placements would be changed around a bit.
