The Kono's get good reviews across the board. The Kanehiro has a carbon core (Aogami Super) which will patina. If you are OK with Carbon steel, check out the Tanaka Sekiso Gyuto's. They have D shaped handles on them, but they are convexed very nicely and cut really well.

Look at the 210mm Artifex, some of the ones with the burl wood handles have already been finished sharpened and are ready to go out of the box:http://www.chefknivestogo.com/riar.html
The Artifex can also be converted over to a Wa style handle, too.
