Exactly same issue I'm trying to solve at moment. I've adjusted the bar backwards on -09 america and at moment it's approx 10,5" pullback and 8" rise. The width of bar seems to be some 34". Still don't feel good. Probably I'd liked to keep the handlebar about on same level, but pullback more. The handlebar is bit too wide, would probably be better few inch narrower. Also thinking if the grips would be near 45 degrees (downwards:) so the wrists would be more relaxed. I wonder if anyone had ideas if this is possibe to achieve by bar change (+pb risers)? Have seen some promising HD bar but lost it. It would really help to see some pics. Keith's black one seems to be kinda what I'm looking for but not sure if I'd wanna keep the original bar.
