There are a lot of mods to choose from now.  Some of the mods are good but others have really crappy weapons and armor.  I only use 2 mods:

HaVoC 1.5.9c

Havoc is one of the best mods ive ever used.  You have the choice of 9 different armors and an array of weapons, turrets, backpacks and a heap of new maps.

Annihilation 1.31

This could be the best mod of all time.  More advanced armors and weapons, new backpacks, turrets etc.  Great mod, I highly recommend you download it.

I think the reason I like these 2 mods is because there is so many weapon/armor combinations available.  You can really give the opposing team a new way to hurt with these two awesome mods.
