So carbon in the handlebar space really only nets you shape options. If you like round bars, you might be happiest with an AL bar given a wide array of options. I think most of the bars in this space are going to be shallower and shorter, with longer drops (meaning they are meant for a longer stem).
Note:
1) that measurements are different company to company - for example a 42cm Easton bar is the same width as the 44cm 3t bar i had despite both quoting hood c-to-c.
2) Flare is not the bar tips splayed out to the pointing away from the bike. Flare is the bars spread away from the, but parellel to it. "Outward Sweep" or "Z-Flare" are the bar ends pointed away from center.
FSA has the Carbon K-wing, which has weird pockets for your palms.
This might be better for you.

I'd suggest looking at the product technical drawings.
