I use Northroad style bars. I'm 47 and find my hands really suffer with any other bar. I also raised my stem, though, so my back is straighter when riding and there's less weight on the nerves in the centre of my palms. This also helps with neck and shoulder pain I get on the first few days of any tour, as the muscles set it, as my back is straighter. The only downside is this puts a bit more weight on the saddle - I use a brooks there, though, and this seems to help in that respect.
