If anyone honestly thinks that Silvergun performance wasn't almost perfect, then they are delusional.
Sour Girl is actually quite good. Not perfect, but quite a bit better than Scott's sung the song in years. Stuff like Silvergun Superman and Big Empty sound about perfect to me. I like that Chester DOES add a bit of "Chesteriness" to the songs here and there, but he's selective about it...
As far as the "not enough deep cuts" argument, I think that's bullshit. They played Pop's Love Suicide, Sex & Violence, Silvergun Superman, Church on Tuesday, Piece of Pie, and Hollywood Bitch. So they dove pretty deep into the obscurities.
And let's not forget that they've practiced a lot more songs than this for the tour... And with Chester, they are pretty much able to play what they want when they want with little notice. I wouldn't be surprised if we see more rotation this time.
