I hope that I don't get flamed too hard for bringing this thread back up. I had lots of problems with hand and wrist pain with my setup, but changing bars did help.

My original setup looked like your pictures, until I moved to the Deda Supernatural handlebars.



I don't have the bike anymore, and the photo is older, but I think you see the flat transition from bars to hoods. I was never comfortable on longer rides until I switched to these bars.
