I know myself, I change from time to time which I shouldn't do. I've got my, and no I'm not a girl, periods were I like to play TF2 constantly, while putting CS:S aside. I'm currently in the TF2 division but I'm pretty sure I'm going to move to the CS:S Division. It has more possibilities such as jail mode, 24/7 Dust, 24/7 Office and my favorite, 24/7 ITALY!! Soooo my advice is, is indeed the advice someone else already mentioned, pick a division which game you play mostly. My choice is based on my feeling, sometimes I'm really in the mood to teamplay and group up with all the whacky, crazy, extremely friendly TF2 players. But I also like to mess around in jail, with the knoweledge that I can go to any 24/7 server and play seriously, with headset on and curtains closed =)
