Besides aerobars and bar-ends for hand positions, you may want to be more upright by swapping your stem for something like
this 30-degree model.
Personally I'd stay away for the double-stem-bar rigging. It's kludgy, lunky, and flugly and probably functionally ineffective, or we hear more how great they are on the road. The only time I see them discussed is in the engineering and building stage.
