I set up my wife's bike with Casey's Crazy Bar from Velo Orange to try to give a swept back position for upright riding but also a more aero position for headwinds. It does provide those two positions, but I find there's a bit more flex in the bars than I'd like when trying to climb in the swept back position (where I usually am when I ride the bike because right now it's set up to pull my 3 year old on his bike using a follow me tandem coupler and I need the wider positioning to keep us stable).
