1...Nf6
1...f5
have a look at the modern benoni...might like it
Benoni 1...c5, Mikenas 1...Nc6 and Englund Gambit 1...e5 might be considered as aggressive.
The Modern Benoni is much better than the Budapest, IMO. Not sure why so many people consider it to be bad, as I have yet to see white get more than a small advantage with best play, even in the sharpest lines.
