Tlaloc. So far I haven't found a better scout rifle; perk of RoF increase when super is full makes it that much sexier ;) I know some will go with auto rifles or pulse rifles because of the "spray & pray" method of a bazillion bullets flying towards their intended target... but I prefer a higher dmg value per shot rather than a higher number of low-value shots. I may be wrong, always willing to try something else, but still it's my favourite.
