When I was setting up my old Raleigh Sprite, I kept a set of Schwinn bars from a Suburban. They have a really nice sweep to them, and were much nicer than the Sprite's bars. The best handlegrips I found were the old 1960s style Schwinn grips- best comfort in the way they felt on the hands and shock absorption. I set them up with Suntour Power thumbshifters- it was a perfect ergonomic setup.

Here- trying to figure whether I liked thumb shifters or stem shifters more:
