If standard drops aren't wide enough try Salsa Bell Laps or the cheaper Moto Aces. These are extra wide and have flared drops designed for off-roading. Or you could look for 48cm Nitto Noodle Bars, but these would probably need to be a special order from the US or Japan. You could combine either with aerobars if you like.

Re. aerobars on the road: they're definitely faster than drops - that's the point. And a lot of people find them very comfortable. But using them around traffic or where there is any possibility you might hit a pot hole is risky; they're banned from most forms of racing because they reduce stability and turning and braking ability. Reasonable cross section of opinions:

This calculator is very useful if your're playing around with performance options:

Your hybrid's position is most similar to the "bar top" setting but probably a bit slower, as you're hands will be further apart and the stem shorter.
