I have a flat bar with Ergon GC2 integrated bar end grips on the touring bike I use for centuries and other distance rides. The bar ends place my hands slightly wider than my shoulders and the regular flatbar grip position puts them at about the same width as my shoulders. I know a lot of people knock flatbars, but I find this setup very comfortable even on long rides of several hours.
My road bike has a Bontrager bar with fairly shallow drops, don't remember the model. I ride the hoods 80% of the time and my hands are at about the same width as my shoulders. The top is set at about seat level or just a cm higher which is comfortable for longer rides, but I'm a clyde and not as flexible as I should be.
