I have Ritchey Biomax handlebars on my roadbike (below, in pink):
They do allow a pretty flat transition between bars and hoods, and I find the anatomic bend pretty comfortable (much more so than the stock Deda Piegas that you can see on the other bike in the picture). One thing to be aware of though, I'm actually considering moving the hoods up a hair on my roadbike, but if I do I'll probably have to shim the brakes -- and that's a bit of a drawback to these particular bars, because of the dramatic anatomic slope there's really not a wide range of practical adjustability for hood placement. I have the hoods placed as low as they are as much because it gives me a good purchase on the levers from the drops as because it puts the hoods in the most comfortable position.
As I said, I like them though. Mine are 38s. Switching from the stock 42 bars really helped.
