I've read a few things on Vest's website. he's mentioned other contests he's done. Specifically I remember him saying for one he came in overdieted, and another some other issue. So to me it sounded like he knew what he was doing.
Rhino has made a bunch of polite comments about Vest, about people looking better in the gym,etc. I thought I had seen Vest on stage before in a pic looking pretty good.
