Some parts are too recent to properly evaluate, but I have a feeling Brad Cromer or Worrest part will probably hold up and be my favorite of this year.
For whatever reason, Shane's stuff from his 9 days or so in Melbourne labeled Not a New Part got me really hyped, and his Levels part was absolutely insane.
