I have the Easton EC90 Equipe Pro Bend bars and they are great! I'd had short and shallow women's bars, but they were 'anatomic' style, which left me just a little nub to grab onto when I wanted to hammer. A note about these bars, though, is that you are only to use them with a 2-bolt stem. Many have 4 bolts.

However, if you are not having issues with your current 38s, not sure about switching to bigger bars. I actually prefer a bit wider of a bar and switched out the 40s that my bike came with for 42s.
