A traditional rando bar doesn't have much flat and starts flaring before the drop so it tilts the levers out. The Nitto rando bar is like this. Because they flare out at the top, the drops are mostly perpendicular to the flats like a traditional bar. These are a nice problem solver for people who keep stabbing their knee caps into their barcons, but I find otherwise uncomfortable.
Then you've got Dirt Drop or Bell Lap style bars where the flare happens mostly down at the drop. This allows you to maintain a vertical lever position. The Dirt Drop is almost identical to a Nitto 176 except for the flare and the heavier guage tubing (I'd wager to say they're a solid 100g heavier than their 176 equivalent).
Then you've got a bar like the Nitto Noodle. They have a sweep back on the flats and very slight flare at the bottom, post drop. 3TTT Morphe bars fall into this category too except they have an ergo drop. I too love the Morphe.
The Dirt Drop and Morphe are both discontinued
