Second set was the best of 3.0, case closed. I know people say that all the time, but this was the real deal. Random thoughts:

Paul and Silas - This worked because everyone was waiting for a Tweezer opener, so it kept the fans guessing a bit longer. Also I approve of any stage banter or nod to members of the audience.
Tweezer - Very sinister jam that ended with a sublime outro that teased "What's the Use?" quite a bit. I didn't mind that they went on into something else, as they had quite a lot left on their jamming plate.
Golden Age - I don't know how to describe the last couple minutes, other than the best sounding thing I've ever heard. There was a suggestion of 2001, but it would've been a rather chaotic beginning to that song. Again glad they simply let the jam breathe before going in a different direction.
Piper > TCB > 2001 - I hate Randy Bachmann and 70's corporate rock, so it says a lot that I liked this too. I treated the TCB cover as kind of a joke that somehow created a perfect bridge between strong versions of Piper and 2001.
Sand - At this point, Trey became possessed by Satan and played one of the best "Type I" solos in Phish history. I have heard enough phan complaints about "the whale" guitar sound. I hope that whale skeptics will hear this and realize the error of their ways.
Slave - Especially patient version was just what was needed after the previous theatrics.
Encore - Was expecting either a Loving Cup or Char 0 to precede Tweeprise, but soon realized that Day In the Life was the perfect choice for this show. The two chaotic swells in this song, both executed amazingly, reminded us what kind of sonic heights Phish is capable of when they are in the zone.
