bullhorns are great, i've ridden and loved my rb021s for a long time, it is important to note(especially when riding in traffic) that you're in a more stretched out and much lower position than you would be with flat bars or risers, i've never ridden with flats or risers but occasionally throw on some porter bars and the visibility difference when it comes to cars seeing you is huge,
the wind thing is crap, bull horns provide for some extremely aerodynamic positions, but it's important to remember(especially when approaching intersections) that you're sneaking through and they may not see you
