That's the funny thing about it. We got stomped on parts 1 and 2, and it wasn't until you (and...Bahamut, I think) switched over that it started feeling even. And then the whole team just suddenly started slaughtering everything that moved for a few minutes.
Your ping issue is strange but not surprising, given Source's tendency to produce inexplicable bugs for no apparent reason.
As for maps, I'll throw in another vote for Gravel Pit. If custom maps are an option, ctf_casbah is good fun.
