Get the trekking bars. I got mine over a year ago and would not go back to a flatbar (for this bike anyway).

If I want more aerodynamics I can put my hands in the forward position which stretched me out and flattens me out. I can use the sides for a middle of the road position between stretched and cruising. Then there's cruising mode (used most often) where my hands are closest to the body and I'm most upright. Then there's all the positions in between.....

You won't lose much to try this great invention - the bars won't be more than $20 and the tape no more than $10. You already have the brake levers... the shifters may be a problem. I would recommend some of the rapid fire ones... So another - wow they are expensive - http://www.nashbar.com/profile.cfm?c...u=21194&brand=

Didn't realize this. But it's much cheaper to go with the bar mounted friction shifters (which you're already kind of used to)
