I have all of them from 2008-09, and the only one I have from '07 is Mansfield, since I live around there. I plan on collecting all of the ones from 2007, but have been too lazy to do so. I enjoy collecting because it's addicting, and I enjoy seeing how they change things up and act differently at different places. My favorite has to be Hannover '08, because they changed the setlist a lot, and there was a lot of energy. I think that there should be a little bit more crowd in the mix, because when they do crowd interactive things, you can't really hear the crowd.
