Variety is the spice of life my friend… I play LOTS of different games and love a lot of different systems… for lighter, flexible games well I personally think True20 and Savage World might fit your needs better then C&C, which is lighter and cool but is not all the flexible (IMO).
BUT games that you should maybe check out…
Warhammer Fantasy Role-playing 2nd ed
Mutants and Masterminds
Runequest (out sometime VERY soon, and I have love many of the previous editions and this looks VERY good. Sort of BRP system but a bit different)
