Well, the first thing is to present the Numb Hands post:

The second thing to check is weight on hands, which can be set by saddle set-back. While pedaling on the flat in the hoods position, can you lift both hands off the bars for a bit without sliding forward on the saddle? If you slide, the saddle is too far forward. I have a longish torso. I have to use a setback seatpost and slide my saddle almost all the way back.
