I ride track bars with hoods on my most frequently ridden bike. But... you don't have brakes... and many disagree with it.
Other bikes are convensional road drops on the roadie, and bullhorns on the fixed conversion.
It depends on what you like, how flexible you are, how windy it is when you ride, how far you ride, etc etc etc etc.... so... just pick a set, and go from there.
