I've been using and enjoying these Velo-Orange bars: Casey's Chromoly Crazy Bar, Noir - Handlebars - Components

Although I don't use the "horns" often at all, but I also haven't had many extended rides on them, yet. I find the sweep to be comfortable, though, and much better than the slightly swept back flat bar I started with. But I don't use drops, and I'm still trying to figure out the horns. I grab them every now and then for a change of position, but I think my whole set up needs a little tweaking, but it does seems like they'd be good for tucking in a bit. If I find that I'm not using them during all day rides, I'll just look for something that replicates the sweep, but lacks the horns.
