Ones I like are the profile century aero bars

These have the solid bridge and point upwards, making them very comfortable. The arm rests are fairly high and attached to a road bike does not turn them into an extreme aero position, but does keep your arms in front of the body to give an aero advantage.
I've used straights, s-bends and ones with a more extreme position and lower arm rests, but these can put a lot of weight on your arms and can be tiring after a while.
