I don't necessarily agree with raising the bars - of course, I don't ride on the hoods.
If I were though, I would lower my bar considerably. With my current bar position, my wrists are placed at an awkward angle if I ride in the hoods. If I lowered the bar substantially (unflip the stem, remove any spacers) I would be perfectly comfortable in the drops and my wrist angle would be natural.
I do think wrist position and angle is the right thing to be looking at though.
