WSM. I think he also feels he may have prepared too much for the Arnold (where he tore his hamstring) and due to the list of events not being sent out in a timely fashion for WSM he wasnt able to prep as much as he wanted. (Its more than just him complaining, Halfthor had similar thoughts)

I also know he is frustrated that WSM is more about who is strong and fast rather than just strong. He likes the arnold because its more strength driven.
