Complex, attacking openings for white?

I'm tired of playing the same old openings, and want to study a new one to play as white.

By complex, I mean leaving a lot of pieces on the board and not just trading a lot off. Maybe something that often results in pawn advances toward the king in the middle game.

Any thoughts? I'm considering learning the English and have never played 1.c4.

King's Indian Attack.

Two of my games:

Robert James Fischer vs Lhamsuren Myagmarsuren (1967) A Tangled Web We Weave (chessgames.com)

theres lots of exciting and aggresive openings for white. i personally like the evans gambit but your oponent could go for the berlin defense instead of 3.bc5. other good options are the smith morra, the Kings gambit (risky), the vienna gambit, and basically any other open e4 gambits and games. like the other guy said, the KIA id also a nice weapon for kingside attacks.
