I have done a lot of work on the dirt-drop bars on my Atlantis (Dajia Far Bars from Velo Orange) to aleviate numb fingers... a friend several years ago had a new specialized bike that had nicely shaped bars, so I looked into it, and discovered a Specialized product called Bar Shapers, which were rubber bits that had an inner radius the size of a bar, and then had thicker area in the middle. They came in two thicknesses, 4 pieces per package, around $7 per package I believe. I think this product is no longer made, but twice I've found old stock at random bike shops and had them mailed to me. This combined with a gel pad along the top of the bars, does the trick for me - gives a nice wide flattish area where my hands rest most often - on the bar tops or on the hoods. So google Specialized Bar Shapers and see if you have any luck!
