I'm also having a hard time getting my hands comfortable on the top bar. I feel like my hands are squished in just a bit too closely to get my wrists comfortable when I move from the brake hoods to the top bar.
Perhaps you need either a little wider handlebar or a different stem? I believe Specialized puts a 110 mm stems on most bikes and I've had to shorten mine to a 80 mm. Just brainstorming here.
