depends...for CTF, good choices are "Happy CTF" or Shadows "Future Evolution" or the default CTF levels...if its battle...there are a lot of awesome packs to choose from (stuff from Spy, Shadow, Dis etc.). or just default battle. oh well...just browse thru j2o and sort by rating



by the way, i think a server like that is more like a meeting ground for everyone than a real battle arena...but still, it should have some quality levels of course
